My main problem with rotations is that they're way to scripted. Especially for DPS. I can't even play dps end game with all the skills and rules they have. One mess up and the dps is shit. Which is why I commend those who beat a3 a4s when it was relevant.

They would be smart to start replacing old skills or seriously consider trimming it down.
Eventually after x amount of expansions we'll reach level 100, and that means 20 more skills will be added on top of what we have. That's something I don't want to stick around for.
