@ Mewtarthio: I can understand that.
But possibly 18 Tier 2 / 3 summons for Sheaim (per sphere / summon even?) might be enough space to field an impressive ammount of units so that they wont be scarce on material for summoning. Even when eating the dreams of big cities
.
If summons cost upkeep, then it whould still make a lot of sense to not just summon alot long before Battle.
And i don't think 18 fully replenishable Tier 3 Summons per Tier 3 Sphere is really weak.
Perhaps that whould even be to powerfull and not to weak as you seem to think. (especially since Tier 2 whould be enhanced massively by it. Since there is no Unit-Limit at that Level.)
Also I think Sheaim will be hugely improved by change to death sphere. Disposable Skelletons en masse right out of the box is not so bad at KotE.
I reckon from 3.1 on the AI Sheaim will do really well (at least compared to other AI). As long as it gets to build some Adepts and promotes them to Death 1. (AI is fond of Combat Promos for casters so prepare for endless Str 6 Swarm in games with no Building requirements.)
Yes, Barbatmos i believe was nerfed because of something along that lines.
Has made him far less interesting. He is not much more than a Sitting Duck now. And the Number of his summons whould still be limited. He wouldnt constantly summon things.
But up to a certain Level I can understand the nerf. In sake of AI and new players.
Poor lad still.

All he wanted is playing a bit.

Bored by his long undead existence.
(on a side note: When the AI can't cope with the game many players complain even in mid-beta (given the Game is so impressive allredy that it hardly seems like a beta. I can see why new players might miss on that one and think its allready complete save for the AI.

).
Wenn the AI can grasp a concept really well and pull of something impressive that really makes one pause like Summon Tiger like mad, Barbatmos killing nearby civs, Avatar of Wrath wiping whole continents, Clan AI using Warrens to great effect or (sorry for the following one Kael. No pun intended

) Archeron running around and making some REAL trouble, players complain as well that it is so terrifying and game breaking / experience shattering.
Quite interesting.
I can imagine that some players will call for a lot of nerfs wenn the AI is fixed at Ice and gets to play the game even remotely right.)
The idea for Life 1 is nice as well. But perhaps that whould make AC control to easy. (Putting a limit on the reduction like with Prophecy Mark - Increase might work though)
