30+ Dungeons

[Duelle]

It's not gear related. My 41 warrior has most of the gear obtainable from every instance, and he still takes a great pounding from trash mobs. Bosses are not a problem, however tanking 3+ trash mobs makes my healer spam like crazy at times. CC is the best option if you have it, I notice a great ease when mobs are slept and we can focus them down 1by1. So use them CC's and pop them cool downs.

I'll agree that damage scaling post-30 hurts. The problem with relying on CC is that not all classes have them, nor is it common enough. With BLM and WHM being the only two jobs that can effectively CC, there's not much you can do if you don't have them in-group.
