I was tanking RFC last night and there were several pulls that ended up aggro'ing other groups that I wasn't accustom to. Of coarse, it has been a long time since I have ran this dungeon in vanilla, and my reference won't play a big part since it is different coding, but on Kronos, the aggro range wasn't as bad. Being that I was level 13 and the mobs are around level 15 could be a factor. Anyways, one pull that seemed to have issues was with Oggleflint. I have been able to pull his adds without aggro'ing Oggleflint himself. Also, I felt the distance could stand from them without pulling aggro was really long.
With fire pits, i could be ruffly the distance a hunter has to be in order to use their range weapons from any fire pit that could cause damage and I am affected by it. Running into Thrall's chamber in Org is really bad.
Anyone else feel the same way?
Edit -- I also would set marked targets for kill order, but whenever the first marked target would die, all marked targets would have their marks removed aswell.
