Answers in greenI'm sorry, I can't agree here.
1) It was on hard. Traps start to hurt on hard.
If traps on hard kill you in ONE shot, get more HP
2) Not everyone has evasion. A perfectly zerg worthy toon may still have to be careful with certain quest traps. If they don't expect them there can be trouble (see point 3).
See answer to 3, they had no reason to not expect them.
3) You apparently disabled them the first time. Despite your comment about them not giving XP you didn't actually say you weren't disabling them the second time. They had a reasonable expectation they would be disabled and not expecting them they could have run through at less than full HP.
Oh I DID say I was not going to bother with them because they didn't give exp. Right after disabling them on the first run. NO ONE COMPLAINED about it.
4) While generally avoidable, lag will always be an issue. I still get hit about 1 in 5 tries. This is an MMO, always assume someone in the party has lag (zerging or not).
So I should be blamed if they lag?
5) And how much effort does it really take to disable the traps (and yes, I play a rogue). For the 30 seconds of work and the simple peace of mind I'd do it (on hard or higher at least. Admittedly for normal any zerg worthy toon should be able to make their way through).
ZERG RUN. On a quest that takes 5 minutes, why waste one on the traps if they don't give exp? I'm not there to babysit them, not my problem if they die somewhere EVERYONE ELSE IN THE GROUP was able to get through easily.
