I know this is a far stretch but how bout creating a separate system between pvp and pve in terms of damage calculations and reactions to environment. So when someone says "Nerf the warlocks" or "Doctrine is op" take the stats and the statement from your customers (that's us bungie) you can Nerf or buff or balance out in one game mode but not in the other. Now I understand from a coding standpoint especially from the old system this is nearly impossible but just a thought for destiny 2
