I personally think TERA has the best combat out there - the problem with that game was...that's all there was to it. Not to mention, while it had the best combat system, imo, the trash in dungeons was a bit tedious because nobody cares about trash anyway. With that in mind, complex fighting against trash seems tedious rather than interesting. But...admittedly, I could deal with that if the game in general just had more to it.
