Look down a lane in quickplay and youll often see 3 to 4 people shooting at once with the odd random hero breaking of on his own. Dont forget that for the pvp crowd crucible isnt casual. Apart from comp all you have is quickplay so thats where the action is.
Well that is not the purpose of quick play. Its for fun. All pinnacle weapons should be banned from it. Its your own fault for the nerf and driving people out of pvp.
Plenty of people have fun in crucible with or without pinnacles. You can have your views obviously but you cant decide how others are supposed to have fun.
