Won't work. It isn't overwatch where you can change class(character) mid-match and counter your opponent. Your whole class argument is moot. You can however change weapon and with that you are closer just to what the devs were thinking anyway, when they developed this game. Its a community problem, the more the majority complain of changes the more bungie will bend to the will of the masses to please customers. You and most of these people agreeing are far too idealistic.
