Hard to buy the reasoning when we all know it's the post slicing nerf whiners pointing their fingers that's causing this. It's not just a pvp nerf, it's a pve nerf also. Just one less option for tanks to keep themselves up.
If this is going to be Bioware's way of dealing with crew skills, why bother wasting the massive time/credit sink into doing these in the first place. My next character is going crew skill free....what's the point?
