There should be no difference in reforging Hit or Spirit.
Thanks, but no. There is actually no information about 2 targets. Theres "single target, stationary", "single target, movement", and "area of effect" aka 3+ targets. So there's basically a cap between 1 and 3 targets. I would love to know what the most optimal rotation would be for this situation, as it seems to be fairly common in both dungeons and raids.
