Having new abilities just to have abilities is bad.
They could have added traits that improve existing abilities (instead of direct replacements because of level sync) and put an ultimate awesome ability at 55 and 60 or even just 60.
Blood of the dragon's proc effect could have been handled differently.
And hosting the servers on a better network would help with lag by a ton. I shouldn't have to pay for tunneling because of their crap. The network host they use is a business cloud full of redundancies. Adds up to lag.
