When playing Evoker, you cannot cast Renewing Blaze when targeting an ally that is out of range (30 yards ish?). This is definitely a bug since the spell is always self-cast with no range on the tooltip.
I believe it could have something to do with the talent which makes it also apply to your nearest ally but even in that scenario it should still be self-cast according to the wording of the tooltip. Also this bug occurs even when u don’t have that talent.
