People don't seem to be too bad about dodging on Titan, actually. At least until the final phase hits where people begin panicking with Bombs+Landslides happening at the same time, or not spreading out in time and getting boxed in by Weight of the Land.
...Assuming you even get there. Like 80% of my groups in the Duty Finder would fail to DPS down the Heart in time to begin with. :/ Not that a premade through /shout was much better until I was a bit of a bitch and remarked that Duty Finder groups do better at not dying in Phase 1.
