koverwatch opinions

i love this game and i know Sin does too so i wanna say a few things that i feel would help the game advance. 1. NERF BOMBERS Hands down the most important fix and i think you agree. I think they should do about half the damage they currently do and bombs need to explode much faster but still random timing, like if its at 5-10 seconds right now i think it should be 2-5 seconds. Too often they just overcrowd the little hallways we have and its impossible to even get in the fight as a healer. 2. ROLE LIMITS I think every role should have a limit of 1 role each per team unless its a bigger game then this can be bypassed. This can be done by not having us start on the shooter role and making the role off limits once a teammate has picked it. 3. TANK NEEDED We need a tank role that does less damage but can take 2-3x the damage as the dps roles, this role can also be disabled for free for alls if we have to consider FFA. 4. MAP FOR KOTH Any Map for KOTH with a circle to capture, must have AT MINIMUM 4 entry ways, i also think its best for the entry ways to not be like a + and more so like an x so both teams have 2 entry ways and it keeps the pace of the game going. This is even more important if the bomber role isnt nerfed enough 5. IDK MAYBE IM NOT A PC GUY but i hate the ability button being shift, i feel like F would work better or something else idk but this isnt a big one, i just barely played this mode and need to get used to it but yeah sin probably already thought of all this just wanted to nerd out
