Controller does not target minions correctly for offerings

Most of the time if you use the controller and you activate an offering it does not intelligently find a valid target (your minions) in fact it attempts to target invalid targets like corpses and then fails to go off while consuming the life/mana for the skill.

If you don't stop turn around face your minions and then cast it it will often fail and even doing this does not guarantee that it works. Since this ability can only target your minions and the controller does not have the control to click on or mouse over a specific minion it should at least auto target valid targets only
