It seemed like a decent game, but these 'revolutionary' things aren't really so. One of the few things that annoy me.
They replaced tank with support or in EQ2 / 1's case, just removed tank as there already is a support role.
However, the issue is, if you're melee... you have to build tanky. The game lends itself to be range friendly. The melee becomes a tank since the mob's AI are rather retarded.
Server wars was already at thought up thing, though this one is server 'invasion'.

Quest system came from Warhammer Online, and then later to Rift, and then now to GW2 with a brand new name.
Skill system based on weapon is something 'new' for an MMO, but hardly something revolutionary mind blowing awesomeness of awesome awesome. Just look at games like Dark Souls where the weapons drastically changes how your character attacks.
Hybridization is that of DCUO, where you have a mix of action and target system. It is not something new.
