Chemist needs a buff. Badly. (part 2)
3) Basically, anything she can do, Iris does better. Aoe heal? Chemist needs to aim and reload, Iris just uses a skill once and can leave it for half a minute. Damage? Iris MELTS, while Chemist either tickles or misses (or dies before she can even shoot her second shot). Damage Boost? Iris has 100% uptime on it with a 4 second cooldown to switch targets. Chemist may have a stronger boost but has to choose to either use her ult to save herself, a teammate, or determine the best person in her team who can make use of the damage boost for like 6 seconds. Her ult is strong but situational and Iris' damage boost never ends.
4) Chemist's most successful playstyle right now is to hide behind cover and just spam everything on her team. Not exactly the most engaging gameplay...
5) Her passive is too slow. That's it. Although she does 50% more healing, you could be burst down before you notice the extra healing because of how slow it is.
Possible solutions:
1) Increase her stats and remove the distance-scaling damage of her shots' AOE. Make it so her heals AND damage deal 1k non-direct hits and 1.7k direct hits.
2) Fix her projectiles. I think it would be better either by making it pinpoint and not arcing like Kazama's or Labula's shots or by making it have the same physics as Hunter's flares. As long as it's not the mess that it is right now.
3) If neither of the first two can happen, simply make her tankier. If her best way to duel is to be up close, give her 6k health and 2 more ammo.
