Am I the only person who doesn't mind this event? It's super easy, and unlike the messenger event, you can't fail it.
Unless the torch glitches and you can't pick it up and unlike the heirlooms/supplies event, you can't crack the exit until it's done. 
I'd rather fail the event than have to gas my poor characters to death in order to ensure we get xp and not a failed host migration screw up.
Other than that.... I love team killing randies by taking the torch and running to the end, Mwuahaha.
I have never seen this happen. I thought it was just anti-veilfire propaganda.
Yea just like when the TR doors glitch because you got interrupted while opening, the torch could glitch if trying to pickup and were interrupted. I have had that happen 3-4 times at least in the past, and Lex was part of some of those games. However, I do like the event better than keeping the F'n messenger alive when he says "I am no warrior" and then charges the enemies. lol (also "Team Kill" time is fun, thanks Lex)
I also like that at least when the VF event glitches you can always die in the gas and get your XP, unlike with the key glitch since most of the time all enemies are dead and if not on FC a host migration is only answer (which fails most of the time). Oh or like when Giants glitch and some PUG/s kill all the remaining enemies you needed to kill yourself/the team, so again the host gets screwed. (Oh and on a funny note when this happens and all aware peeps are either a Silent Sister or Saarebas then not being able to go "Over Here" is really helpful...lol Keep killing Mr. Randy the red skulls are coming for you! Muwahahah)
