This means that you get comps which simply are tons better than others, such as RMP or RMS right now in WoW. As for longevity, I think large scale pvp has more longevity, because it is so much more diverse in approaches to winning. In arenas, you have a set hierarchy kill order most of the time, and pretty consistent strats, but in large scale pvp it is never the same. Within one game, you could have a 1v1, then a 8v5, then a 3v3, all the while different players will be popping in and out, changing how you have to approach the battle, and all of this happens while you need to be completing an objective.
I believe arenas would be a bad direction to go, it creates class imbalance, and really destroys certain classes ability to pvp, which is against the whole idea of an mmo.
