That was my battle indeed ! But don't draw conclusion too fast.
I think with 16MR i have a 20-25% chance to stun your guy.
i had like 8-10 astral casters (not 4^^) so i was expecting a couple ettins freezed every turn maybe a bit less. And i think it's exactly what happened.
But i'm sure you ll get your revenge, in this game or in an other.
