So, the boss should enter stealth when he summons/revives little birds, but he almost never does for me. Not even on the first cycle. He only goes into stealth like 1/5 times.
It doesnt matter if i kill the adds or not, he almost never goes into stealth and my team keeps attacking him instead of the adds.
Its practically impossible to clear harder stages because of this, as i cant make my team target the adds when they revive and the aoe damage simply isnt enough on harder stages.
Hopefully, im just dumb and missing out on something obvious, but it really seems like something is bugged.
