Unfinished beta, but fun to play for a while.
Sad part is the game is clearly an unfinished product, which needed probably about another 3 to 6 months of development time. It's not bugs so much as many of the abilities and equipment stats are meaningless and useless, not balanced even close to what they should be. An example, a party buff that gives your party 0.6 damage increase, that is hardly useful at level 1, let alone level 20 at which it still hasn't been upgraded. Another ability heals my Conq. 1HP every few seconds in battle which probably ends up giving me about 4 or 5 HP at the end of a one vs one battle, when I have about 1000 HP this means nothing.
There is more of this type of unbalance with other classes, but this gives you the idea of how unfinished the game is.
Maybe worth $50 for a good month of fun play, but beyond that, $15 is questionable at this point until they finish the game.
