PVE and class stacking .. I really dont see it as being an issue. I parse everything i do just for my own personal improvement, I also use it to ask others what they are doing to generate their numbers. I have come across many cases where competent dragoons and Monks out strip my bard by 10 to 15k even when I don't sing a single song.

I wont deny that Bard have it a bit easier as far as movement... But does that mean they are overpowered or just a little more flexible.

As far as tanks go.. lets be honest some tanks are built for longer fights and some are not. This is not something that is new
