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

I'm above letting people die, but I'm not above giving them a scare. I totally plan to save someone who pulled for me...but only after they've taken some damage themselves. Usually that puts a stop to it without ever having to say a word and without slowing things down. Straight up letting people die though because of this is indeed petty.

See, that doesn't really work. If I happen to pull aggro, I'll just pop Bloodbath and/or Second Wind. Three extra mobs aren't usually enough to do anything significant they wouldn't be nearly dead by that point. From a healer perspective, I actually like DPS taking a smack or two. Less autos on tank and I'll catch them with Assize/Indom/Star anywho. Or they can just sit at half HP. As long as the tank rounds them up at some point, they can sit at 1% for all I care. This tactic will only scare Range DPS but they can just kite them around to avoid autos.

At the end of the day, it's still pettiness. But if you're pulling at least two packs, you aren't going to see many people pull ahead of you. So it's rather a moot point.
