First time experience soured

Also, before the first teleporter, tanks just ran through mobs and nobody fought anything.

That's always what happens in Praetorium. People don't bother with those mobs because they can be skipped easily.

Saddly, Prae is an "old content", and people rush throught it because they end up here thanks to their roulette. It gives a lot of exp mais its really time consuming. I understand your frustration, but all we can promise, is that you'll get a better experience with higher-leveled dungeons and raids (MSQ-wise, not meaning endgame contents).

Also if people managed to attack the boss a few seconds (up to ~5) before you're out of a cutscene, it can be because of lags. Not everyone in the instance gets out of cutscenes at the same time. I know if I alt-tab while the cutscene is on, I get a little lag that eats up to a few seconds, so people get out of the cutscene before I do.
If it happens up to a minute before that, that's just a guy exploiting a bug and he should be kicked and reported, simple as that.
