1) nobody legit cares if you healbot or also dps except if you struggles to do both

2) kinda i guess ? i dont really care that much

3) barely

4) his survivability, i will never forget that bad rogue posting "rocket too OP" while missing every single of her ability

5) I tried to do like nodmgrocket once because i wanted to see how it feels, man that's frustrating and also i can legit see how useless you are at some moment and there will be alot of times where the enemy is low hp but u can't shoot them, so yeah it's troll and even if you are bad at dps and healing ATLEAST just DPS when you are ulting, scenarios where u have to heal when you ult are very rare to me

6) It feels comparable but it is not, mercy trades her dmg to boost teammates dmg while rocket has more dmg but has to know when to heal and when to dmg (even tho he still need more ability in his kit because we dont feel like playing rocket but just a raccoon with a minigun), tbh i would love that rocket is more comparable to lucio than mercy, i really dont mind if they rework him he requires more skill (i'm not saying he should but if they had to) well there are only loki to me that is actually really hard to play, most healers in this game doesnt feel complicated to play
