First time being kicked from a dungeon...

[Stepjam]

Don't worry about getting kicked once. It happens sometimes. I've been kicked once or twice for little to no reason. Only start being concerned if it becomes a repeated event. Then consider whether you are causing a problem in some way that makes multiple unrelated groups want to kick you.

First time I believe I got kicked was on Omega 11 normal. It was near the start of the cycle and we got destroyed on our first pull. I made a small joke about it, then about 10 seconds later I was suddenly back in the doman enclave.

Also, just in case you didn't know (since the game does nothing to explain this), you actually have about 5 seconds or so of immunity when you are rezzed as long as you don't take any actions besides moving. So if you find that the spot you are being rezzed in is about to be covered in a big AoE that'll go off in a few seconds, don't attack the boss or use any other skills until the attack goes off. As a slight caveat, debuffs and knockbacks will still apply, so be aware of that, but damage will not. So if for instance, you rez right on top of a Titan landslide, the attack itself won't do any damage to you, but you'll still get launched off the edge to your death.
