New player here. I reached Titan in story mode Saturday. I was partied with my friend who was the healer and the 2 DPS were through the DF. The lag was unbearably bad. I'm mean, beyond ridiculous. People were getting knocked off who weren't anywhere near the attack cone. We spent the entirety of the 90 mins and still couldn't do it. We went back a few hours later and the lag wasn't as bad and we did it but still, I've never played an MMO where instanced arenas lag like crazy. The over world? Sure, if it's busy. But this is a tiny instance. I don't get it.
