Reverse communions are totally reasonable to me since I played Dom3.60 Yomi mages
I never really played to this point but I guess this just means your screen is full of 60 individual mages you need to move around?
It's not even the worst it can get. Communions an' shit required a good focus, and once reverse communions were a thing once, where you used the communions to spam buffs to the mages to optimize spellcasting. 60 Mages is a lot, but Evocation spam armies usually ran in the 30-40 mages count for midgame (imagine Air mages acting with proper support and Storm power, crap was terrifying if you didn't have counters). Back in Dom4 there was even gem baiting, scripting specific attacks with remote teleport/cloud Trapeze rituals to get the enemy mages to burn their gems before the battles so during the "normal" movement phase they would not have gems to cast battlefield spells.
Or the abuse of the casting order to get your Battlefield spells working before the enemy did. If you want to go full sperg, Dominions has the depth: but it becomes draining fast and lategame turns if taken very seriously can require hours of planning.
Malakal is a veteran so he can probably tell you even wilder stories. Hell, he's still a minor meme on /domg/.
But when I hear stories from Dom2 it gets wild for me, Norfleet would be the guy to ask for those, apparently he was so good with the game's economy they banned him for it.
