Combat in XIV is not
fundamentally broken. Some things (enmity algorithm, effects of elements, class balance) could use adjustments - and they're getting them, but it's not fundamentally worse than other things on the market. It's fundamentally the same system that's been in every MMORPG since Everquest. Yes, games like Guild Wars 2 and Vindictus are breaking that mold since technology allows them, but that doesn't mean the old system is
outdated and should be done away with entirely.
Maybe it's just because I play a healer, but I actually find combat an extremely interactive, nonrandom, strategic experience. The UI needs a significant rework, but hey, it's getting that too!
