Let's face it, the Carnivale should never have seen the light of day. It depresses me to heck when the developers forget this is an mmo.
A lot more of the Blue Mage skills should have been open world.
If they wanted all Blue parties, then the class should have been able to properly diversify at level 50.
But, the biggest gripe is the level cap. This limited class feature is simply an awful idea. What exactly is the point?
The only thing I can think of is the lack of resource or motivation to produce a fully complete new class - and that is worrying.
