As of now I find it quite fun. I'm sure that will pass though. I agree this seems like one big mini game. Doesn't seem as if they put much effort into it.
I've put some thoughts into it, I think that the Dungeoneering skill will add another element in the game, including a few little weapons and stuff, but overall it won't replace the wilderness and getting 100% of your opponent's drop. R.I.P runescape
