A lot of the complaints stem from the fact that you have to use 2 slots to use them effectively.
How about you change the ability use in such a way that you have to summon them once and if you switch your bars the pet go idle. At the Idle stage they can't do anything and you don'T get possitive effects from them but can still be killed.
And if you switch back again they will awake, if they died you would have to resummon them.
Thoughts?
