will having the balance and skill design teams working so close with the pvp and wvw balance team help create a better understanding of abilities/class mechanics that can be useful in all game modes and have better throughout ways to combat the difference of using skills on AI and Skills on Players.
e.g scrapper had a mechanic that was very focused on interacting with players but not as useful in a pve environment
renegade has summoned spirits that work well against AI but not as effective in game modes with aoe CC and damage that get them destroyed
other issues like scourge with its over heavy boon converting that becomes problematic in boon heavy game modes over say PVE where it as little effect
what I am trying to say is will having the teams working closer help stop future design choices that focus on one class type being either over effective in one game mode and under effective in another.
