They won't get more loot, because the amount of loot that is not dependent on LS/DS is far, far more.
Oh the companions. /sigh As awesome as it is to actually equip them, there will be problems with pugs. They will roll on your gear because the companion is an extension of your character, and thus, can be thought of as your character and able to roll on it.
Yep. It'll happen.
I won't need to worry about it, because I run a guild that doesn't put up with greedy pricks. But I really do feel sorry for people pugging.
