Personally I find it completely anti-fun..
so what if the AI can handle it better. you're in the middle of a good game, having fun with late game units and suddenly someone wins. bah.
I suppose its ok if you can avert catastrophe by destroying the enemy city in which XXX is being built, but the AI won't be able to handle THAT, so whats the point.
Also, I'm not sure I understand the need to fiddle around with the tech tree. what do you gain by dividing it to to trunks? dunno, sounds redundant to me..

Hm alright, and regarding armaggedon spells, well, I reckon they could be more powerful.. I got my mithril golem killed by a couple of heavy crossbowmen and some mercenaries :/
And spells like the one that reduces pop and destroys land and such, well, I never tried them because I couldn't see the point.. I think I missed the part where it says they only affect enemy territory and enemy cities.
a big kickass endgame unit for each religion would be nice
* Perhaps a tree-ent elder council for elves.. 10 incredibly powerful ents that come with shock 2 and cover 2 promotions and can bombard cities (throwing-huge-boulders-at-the-orthanc style) for 100% of the defence bonus in one bombard action.
* Mithril golem for dwarves is perfect

I reckon it should be the strongest unit by far (like 200 str), but slow and without any special abilities, and perhaps very limited ability to heal.
* Demon Lord for veil, which is incredibly powerful, can teleport across good distances and comes with the inquisitor abilities and the immortal promotion.
I'd say Avenging Angels or something like that for the order but I reckon they're not 'good' as such.. so perhaps something else.. maybe the order endgame unit should be a 'Righteous Crusade', and when you finish building it you get a +20xp to all your units and all units you train from that moment on.
Octopus lords should get some kind of crazy.. well actually they should get an octopus lord
Maybe it could be an insane spellcaster water unit with spells that have 100 movement, but pretty weak physically (still much much stronger than any other regular unit).
He could just sit in the sea and destroy cities by remote
These bastards ought to be able to win you the game almost single handedly
