At the time, sure I agree. Now? Not really. There's no real risk in places like Seb or HS or Chardok. We know every patrol, every static spawn, every safe point. The only reason we die is because the server lagged, at which point evac is useless anyway. Again, I'm not saying it's for everyone, and it certainly might not have been the case in classic (I played a shaman, who also never had gate loaded, during live classic).
All of my adventures have ended successfully on P99 as a wizard. Sure there have been some wipes, but none of them would have been prevented by an evac. I've not made a single person miserable with this viewpoint, to my knowledge. Never once has a situation demanded the need for an evac, and the group said "goddamnit, why didn't you have evac?". Never happened. Ever. Not even once. It didn't even almost happen.
