If I'm grinding content over and over again, I'm not going to slow down every time there's a newbie in my team. THEN AGAIN I rarely ever tank so the pace normally isn't up to me. I also do not feel like it's my job to hold-hands and guide every newbie through a dungeon either. I feel it's their job to make their experience the best as possible by either doing research or making a premade to ensure the speed they want.

I know someone's going to say "Well you should ensure you get the run you want blah blah....". I do. Most of the time I'm in a half or full premade. But when my friends are busy I PUG it, and I've accepted that sometimes PUGs are fast and sometimes they're slow. That I wont have any control over the pace unless I tank. I may not like slow but... /shrug
