It's not the players that are the problem, but what the game demands of them.

Why should a hunter know about other stances when they get along fine in strength? Why should the champs know about ebbing ire etc when the game allows them to run in all guns blazing in fervour? If the game were designed so that encounters could not always be beaten using pure dps then people would start thinking about how they play.

It ain't the players, it's the system that needs tweaking.
