Over the weekend I went on a Naxx10 guild run - the first for quite awhile since I'm usually busy on weekends.
It was also my first time for a LONG time kiting more than one mob - I don't think I've done multi-mob kiting in a raid since Razorgore, and even then it was only 2.
From my perspective, my multi-mob kiting skills could use some work.
I got hit more than I would have liked, I was a little slow in the beginning picking them up (how healers manage to generate enough aggro for a zombie not to respond to an Aimed Shot from me almost as soon as they're out of the gate, I have no idea) and I even had the 2nd hunter dropping Frost Traps to help me out.
My guildies assured me it was one of the smoothest kills they'd done, so I guess I did OK.
"OK" isn't good enough for me personally though - I like keeping my hunter skills as well-honed as I can get them. The next run I do I'll be aiming for zero hits (or as few as possible), even if I only have my own Frost Trap to do it with!
