Other than lag, Titan is easy for DPS non-casters. The lag is an issue, but half the time, I see people not paying attention until it's too late. They get the tunnel vision and slip. Happens to the best of us. Being a WAR having to go in as a DPS sucked for the heart phase, but not really. We did not preload limit break because we were more concerned about the tumults catching up to us on the back end. So no limit break on heart and still shattered it. For most of our fails, it was due to being in bad, and no one complained about the lag, because we know when we slipped up. Granted, this wasn't a DF group, but this wasn't a carry group either. Well, it was for me. lol. At least I made up for it in always being able to deal damage, and avoiding bad 95% of the time. Plus, I can take a hit and get back almost 2k without the use of defiance/IB. WoW was good in regards to training you to get out of fire.

TLDR: Tunnel vision bad. Lag worse. You can beat one of these things.
