I'm still surprised nobody has pulled the classic "Summoner is overpowered" line based on being able to perma stun stuff with 18 Summoners. They always pulled it in regards to topics like "Why not remove perpetuation?" or "If our astral flow pacts are so weak, why don't we get them on a 20 min timer like the DRG update did with wyverns?".

I guess it will always be that whatever is in the game (even the test server) is balanced, and all suggestions are overpowered.
