I can get used easily, no prob for me, but I kinda quit L2 (maybe 1 hour or less every week) so my vote doesn't count.
But:
NcSoft understood that Kamael was a failure, and it didn't augment the number of players, it just was an unimportant update, but they spent more money that you could ever imagine for its promotion.
With Hellbound, they are trying to fix what they did with Kamael, and I think they are doing quite good. Now players can sub without thinking of the result, cause the more you subclass, the more profits you get now.
After all her mistakes, NCsoft is now more mature, and after all the reduction in sells and players, we will now start going up, and L2 will regain its previous glory...
