to a degree, yes
it does a good job with the lore (that i know of. not really a fan of the original work enough to obsess over everything the guy wrote), and the classes are unique even if their functions are not.
the warden class is kind of fun.
you use two powers in a row and that unlocks a third one which is related to the previous two.
for example
right now i have
attack
defend
taunt
as my base attacks
if i go aa, i get a super attack as a combo follow through
if i use, dd, i get a super defend.
tt, supertaunt and DoT.
if i go ad, I get "the boot" which has a chance to stun the enemy for a few seconds
if i go da, I get a healing spell for self.
nothing for mixing taunts with attack or defend yet.
it's kind of interesting and requires a bit of strategy for things like crowd control.
