I'm not sure they should remove the stamina system. It's fine the way it is, I've never had any trouble adjusting to using it.

Now if they added auto-attack I'd like to see them either reduce or remove the stamina cost for the normal attack and balance it's damage accordingly. While using a gamepad it is annoying to have to move back to 1 every time you want to use a regular attack. Adding in auto-attack allows us to hover around other skills we want to use so we can respond more quickly.

I don't think they should remove required/favored classes. In fact we know they're moving towards more rank/class specific gear and I think that's much better. Removing requirements brings us to the original problem with the armoury system in regards to gear in that it has almost no structure. It suggests ranks and classes but it does not enforce it in any way, leading to people with either no idea what to do or wearing anything they want and wondering why they're getting 1-shotted.

I don't think shield blocking should be automatic, I think it should be a stance you can toggle. Hit the skill once, shield raised. Hit the skill a second time, shield lowered. Sure it would negate the need for the Gladiator guild mark trait but they could always change it to something else like increasing the block chance or something of the like.
