Wanting higher skill floor and greater returns would both make the warrior more powerful and distinguish the great warriors from the good warriors. Currently it has the largest self heals, highest dps, exceptional mitigation and aggro and the skill floor isn't really that high for the class while also having almost no negative trade offs for any of this. This makes it the easiest to use effectively. Im not saying to nerf any of this, im saying increase these things while adding a layer of depth and complexity to a degree that would make it more powerful for those who know the ins and outs of the class. The trade off being that those who weren't as good wouldn't see as much efficiency from the class but this is something that is already true for the other tank classes and most classes in the game. Granted this would likely result in some backlash by the ppl who like "ez mode" results much like the when bard skill floor and drg skill floor increases were implemented but that's to be expected.
