Let’s start with the “hide and rez” assertion.
There are two ways to interpret what Jeff Kaplan said in that video regarding “hide and rez”. One way is that he is suggesting that Mercy players were routinely hiding as soon as they had their ultimate fully charged, which he disliked. The other interpretation is that Jeff didn’t want a main healer to “stop healing for some period of time”. Both interpretations are poorly thought out, and that lack of thoroughness has led to both concepts reappearing through the successive patches to Mercy following the rework.
Addressing the first one… Partially because I am feeling a little bit lazy at this time, partially because I stated it beautifully back on August 12th, 2017, I am going to quote myself from the old forums when I discussed “hide and rez”:
“It’s just hide and rez.”
This quote illustrates that the person saying it has no idea what they are talking about. No, it’s not an oversimplification, it’s just plain wrong.
“Hide and rez” is a great strategy… assuming your goal is to get wiped after the resurrection. Hiding turns the fight into a 5v6 with a main healer down. Any competent team would be able to walk through your team without expending ultimates, except to counter any ultimates expended by your team. The enemy team already has the positioning advantage and the first shot after the resurrection. “Hide and rez” would also give them the advantage of more ultimate abilities. Doing so sets your team up for failure.
A good Mercy sustains her team until they can no longer be sustained, or until she can no longer do so safely. By doing this, she allows the team to bait more ultimates before dying, giving your team the ultimate ability advantage after the resurrection.
A team playing against a hiding Mercy would have a significantly easier time dealing with the opposing team, as Mercy is putting her own team at a disadvantage. It wouldn’t even come down to being aware enough to consciously notice the 5v6 (although most players should be able to recognize a 5v6 when they see one), but a matter of knowing how much force the team needs to apply to overcome a given resistance; if the enemy is crumbling, don’t expend limited resources to push a structure that will fall on its own.
Because the opposing team is already at a numbers disadvantage in the initial fight, pushing into them without using any ultimates, except to counter ultimates expended by the enemy, will be sufficient for eliminating the opposition. This further leads to more loaded ultimates, as killing 4-5 enemies in a 2-2-2 composition is roughly equivalent to 1500 charge in HP. That is also excluding additional charge gained through allied healing and allied damage through enemy healing. Combine this with the absence of a need to expend ultimates, and the team with the hiding Mercy is revived looking down the barrel of an incredibly large gun, has no time to draw their own, and is in a poor position to capitalize on it even if they did have the time to draw their own.
As a result, hiding prematurely was detrimental to the team’s chances of winning the fight in the long term, even if it was riskier in the short term. It was a misuse of an ultimate.
To add some perspective to this, using “hide and rez” as a reason to remove Resurrect as an ultimate is about the same as using the fact that some Pharah players Barrage themselves on occasion as a reason to remove Rocket Barrage.
By this interpretation of Jeff Kaplan’s words, Blizzard’s intent was to prevent Mercy from leaving the fight, keeping her engaged. Rather than giving more reason to stay in the fight through modifications to Resurrect as an ultimate and the introduction of a decent E ability, the balance team decided to remove Resurrect as an ultimate entirely, and here we are.
Did someone say Valkyrie?
If the intention was to keep Mercy in the fight, why was her ultimate, which punished hiding prematurely and rewarded active play, replaced with an ultimate that rewards staying as far from the battle as possible?
According to this interpretation of Jeff’s words, the developers’ statement is, “We didn’t like how some Mercy players would leave the fight before using their ultimate…”. This statement is then finished by the patch history with, “…so we replaced the previous ultimate with one that is best utilized by leaving the fight”.
Let’s examine the second interpretation.
“We think it’s wrong to tell a main-healing character to go off and hide somewhere and stop healing for some period of time.”
1:32 - 1:42 of that same developer update.
The bold section is the one I am focusing on. Let’s pretend that the first interpretation is incorrect, and assume that Jeff Kaplan doesn’t want a hero to stop doing their main job for any period of time. In this case, the assertion may have some merit to it, as there was often a 3-5 second break in healing before Resurrections. This happened for two reasons, both of which came down to practicality:
60 health/second will not save the team from the incoming enemy ultimates.
Mercy’s healing/amplification beams are obvious and will lead the enemy straight towards her.
The would often result in the Mercy player staying further back or taking cover, possibly substituting healing/amplifying with whatever damage they could deal with their pistol. She would then use Resurrect and finish off or severely weaken a target they shot at before the Resurrection. In these scenarios, there is a short duration in which not doing Mercy’s primary job was the best way to use her.
That’s how it looks in a vacuum.
Look beyond just Mercy, and most heroes often perform very similar maneuvers to reach the same goal. Some examples of this are Rocket Barrage and Death Blossom, in which the player stops shooting at the enemy (their primary job) to reposition, obscure their position, and gain the advantage of surprise when they use their ultimate. This then begs the question: Why weren’t these ultimates changed for the same reason Mercy’s was changed?
The stupidity doesn’t stop there. We once again have a statement that identifies a perceived problem and proceeds to contradict itself through the actions of the developers:
Developers: “We didn’t like how Mercy would stop healing for a short duration before using Resurrect…”
Patch notes: “…so we removed Mercy’s ability to heal for an additional 1.75 seconds leading up to Resurrect’s activation.”
If the developers wanted Mercy players to heal more leading up to a Resurrection, why did they make it physically impossible for her to do so?
One interpretation of this argument brings us an assertion built on the ineffective use of an ultimate as a reason to change the ability; an assertion that appears to have been said once and then disregarded with the following patches. The other interpretation yields an assertion that is a double-standard that has also been disregarded in the following patches.
