I'm gonna say something unpopular: I don't like to rush.

[Vahlnir]

Alright, so...You don't like to rush. However, you are fine with handling big pulls. You are contradicting yourself here, so which is it?

As to the rushing vs taking one's time mentality goes I don't really care all that much so long as the dungeon/raid timer isn't draining excessively (i.e. 25-30 minutes left on the timer at the time of completion, or not at the time of completion). I would argue that 20-25 minutes from start to finish might be too long for most, but not everyone's skill level is the same and I'm a pretty patient guy. If a dungeon or raid takes a half an hour or so then that's just how it is. Do I wish it could have gone faster? Of course. But I realize that random people will always be random through the DF. Sometimes you have to play with the cards you've been dealt. Such is life.
