You’ll need to do some reading then. 
The “solidified” idea I was referring to is the one I posted in this thread. I refer to it as the “most solidified one” because it was the most-approved choice among the people who participated in The Drawing Board; a Google Document created and shared among about 40 Mercy mains to come up with and discuss ideas to create our ideal Mercy rework. After about a two-month period of adding and criticizing ideas, we brought it down to a vote, and in the basic ability section, this idea was the one that we collectively decided was the best.
To post it here…
"New Basic Ability - Pacify:
- After a .5 second wind-up, Mercy launches a single hitscan attack from her left hand.
- The projectile’s hitbox size resembles that of Symmetra’s secondary fire.
- The projectile deals no damage upon impact with an enemy. Instead, it applies a debuff that reduces the base damage dealt by the target by 33%. 100 damage is reduced to 67 damage before other damage amplifiers/reductions are factored in.
- This debuff lasts for 4 seconds.
- The projectile does not persist once it hits an enemy. It is only able to affect one enemy for each use.
- The projectile is blocked by barriers, Defense Matrix, and Particle Barriers. It can be deflected by Genji’s Deflect ability.
- 10 second cooldown. The cooldown begins after the ability is cast.
- There is a .25 second wind-down time after Pacify is launched.
- During the wind-up and wind-down times, Mercy is not able to use her staff, her pistol, or Resurrect. She may use Guardian Angel, however.
- Does not affect non-player entities and constructs (turrets, Rip-Tire, Supercharger, etc).
This ability came with some concept art:
This ability functions similarly to Ana’s Sleep Dart in its cast, but the projectiles and effects are very different. Because Mercy is supposed to have a low skill floor, the hitscan weapon type and large hitbox make the ability mechanically forgiving. As a result, Pacify’s 33% damage decrease for 4 seconds is less effective than Sleep Dart’s disable for up to 5.5 seconds.
That said, Pacify still has a lot of playmaking potential when mastered. For example, when used on a target that has been Nano-Boosted or Supercharged, the damage increase that Nano-Boost/Supercharger has on that target is completely negated for the next 4 seconds (100 DPS -%33 = 67 DPS + 50% = 100 DPS).
Pacify also drops Widowmaker, Hanzo, and Pharah’s weapon damage below the 2-shot (body shot) range for 200 HP heroes. If used at the right time, it can potentially save an ally’s life."
While I fully support the above ability proposal (which wasn’t my idea, I should note), I personally would like to see a cleanse ability or a form of anti-CC added to Mercy’s kit as a basic ability. We have an abundance of CC in the game right now, and only 3 abilities total (two of which can only be cast on themselves) that can reliably protect against CC. A cleanse or anti-CC would fit Mercy well, and it could provide some relief from some of the abilities that players hate being affected by.
Personally, I would like the cleanse/anti-CC to have either a mechanical skill requirement to it, even if small, or I would like it to require a level of prediction to use it effectively. I don’t want it to be simply a reactive auto-target ability.
Some other ideas I’ve seen thrown around that I could get behind are a single-target burst heal, a fire-and-forget heal over time, a modification to the functionality of Mercy’s beams and pistol (would require pros and cons for each version to prevent one from being better in nearly all situations), and a reduction to the damage taken by an ally. Some of these ideas can be crossed to create hybrids.

everyone called him useless back in the days. It was 100 percent Lucio/Mercy.
