Your friend is right. She’s a very powerful character, and her ultimate is nothing to sneeze at.
They can’t boost her healing during valk because that would step on Zen’s toes. They can’t buff the damage boost because then she’d step on orisa’s.
However, when you valk you, in essence, get to pocket your entire team which is pretty freaking powerful if you know what you’re doing and your team isn’t a bunch of idiots that spread out too much.
This is where you lose me. You will lose me here every time because Valk is very powerful.
There are two kinds of support ultimates: Invincibility and Assist.
Invincibility ultimates are like Zen and Lucio. When they go off, the other team might as well stop for a few seconds because there’s not really anything they can do until the ult runs out (barring a few very specific counters like EMP and Bio 'nade)
Assist ultimates don’t make the enemy team run away and hide from your DPS. They just make their job’s harder. Much harder. Brigitte, Moira, Ana, and Mercy all have assistance ultimates. They differ from invincibility ults because while you can be killed during them by just about anything, they tend to stick around a lot longer or just do more things in general.
Brigitte’s armor buff only goes away when you take damage. Meanwhile, Nana-boost makes the target better at pretty much everything, and Moira’s both heals and hurts at the same time in a fairly large area.
Mercy’s ultimate isn’t game-changing in the same way most of the others’ are, but what it does do is last forever.
F o r e v e r. 15 seconds is an eternity in a teamfight, and her enhanced mobility cannot be understated because it makes chasing her down almost pointless since she will get away most of the time.
The reason you lose me with the “her ult is weak” argument is because of the duration. Her ultimate is completely unique in its application and classification due to its duration and people want to take that away.
This is why my response to “mercy isn’t fun” will always be “go play something else then”.
If you want your ult to make everyone invincible, go play zen or lucio.
If you want your ult to kill everybody as well as support, go play moira.
If you want your ult to buff the hell out of a single target and make them a nearly invincible engine of destruction, go play ana.
It’s why they’re there.
I’ve seen the following suggestions for Mercy’s ult:
- Remove the chaining and buff the effect.
The intent of this kind of change is to turn Mercy into Ana. More healing on a single target makes that target invincible, much like nanaboost, while vastly superior damage boost…well…is also nanaboost. If that’s what you want then go play Ana.
- Make her valk heal more so she can compete with Zen.
Go play Zen then. If you buff Valk so that she’s more like zen you make zen redundant. Go play Zenyatta and get it out of your system. Or Lucio. They both do what you want in an ult.
Just…stop playing mercy if she’s not the character you want.
Just stop.
