Not gonna happen. Put it out of your mind.
You can't "mess up" building your profession in this game. You can re-spec your tree
if you don't like things. That is enough for most people.
Want a different AC? The solution is rolling an alt.
though i do agree with you, there is a major floor in that, we dont have 16 character slots to create every AC in the game on one server on the same legacy, and though there are mirror classes, and the abilities have identical effects as their mirror, the animation is different and I would want to see that, and one last thing... if anyone thought I couldn't make enough end game toons to fill the limited 12 slots available on the server I play on, oh how wrong you would be.
