True, there are games that separates changes that are made in PVP from PVE. So one stat, ability, nerf/buff in one are separate and only apply in the other and vice versa. Idk why Bungie could not simply put the time to get the coding down across the game for that to happen. It would be justified in additional development time, since it would literally fix all these threads about PVE players getting shafted for changes that are primarily made in PVP. Then they can use what they have learned and implement and improve for Destiny 2. It is true IMHO, that an online game with PVE and PVP modes should have a system where changes in PVP would not affect the PVE side.
