Some healers make me panic

[YitharV2]

I personally generally start hard-casting heals at the 50% HP mark unless I have CDs up - Not because I need to, but precisely because I know tanks tend to panic when their HP gets much lower. If I let them drop much lower, they commonly start using all their CDs at once >_> But casting any earlier could be overheal if I crit.

Same. If a tank can't handle being at 50% HP, they need more practice.
