On live the -5% periodic healing is gone from the tooltop.
I'm sure I read all blueposts etc so I went and checked wowhead, wowwikki and they both list:
"and reduces all periodic healing done to the target by Y%. Lasts for 12 sec. Stacks up to 3 times."
Tooltip error?
Hmm wowhead had updated this, weird when was this change implemented? During my wow break this summer or?
