Not going to weigh in on what’s broken, needs to be fixed, etc. since that has been heavily debated to death on the forums. Are there some bugs? sure. but the class is currently playable.
All I wanted to say is.. the mesmer is a complex class. I really want Arenanet to take their time and do any fixes or revamps properly so the entire system of traits, mechanics and skills work together in a fluid, harmonious fashion instead of putting some bandaids on various traits and skills and saying FIXED! And then not looking at the class for 2 years.
