Hi,
It would be super useful if when you are at the maximum number of a minion (I notice it for flame wraiths) and you summon an incremental one, that the one that dies (to make room within the cap) is the oldest one. It appears to be random which one it kills to make room for the new summon. This makes it more difficult to manage in scenarios like in arenas. Often times you can find yourself all of a sudden missing your defensive coverage on a side/angle. If you’re unlucky, sometimes it takes 5-6 casts just to get more than one wraith in a new casting area, if it’s just repeatedly killing the ones you just cast.
Thanks for considering!
