I'm a big fan of Flare, the level 8 warforged sorcerer hireling. I use him for a good amount of time for soloing on any warforged character I play, and sometimes on others because he can repair the both of us while contributing damage.
Anyway, after Update 8 I've noticed that sometimes he will go through the casting animation but fail to cast the spell. Usually I notice this when I try to make him cast Haste.
Did he perhaps reset his enhancements and forget to take Inscribed Armor again?
Might want to fix that unless this is intentional. Goodness knows I've paid him enough plat over the past few months for him to be able to pay for a reset.
