No player wants them to, but it seems P-dox wants them to. Alas.

Mongolians should appear during civil wars, should suffer attrition, should have stacks not exceeding 40,000 troops, should pay attention to attrition, and should not combine stacks except for short periods (to defeat another large stack, or to storm a fortress).
You need to gather your army in steps, and throw them into battle stack by stack so that you don't lose people to attrition on the march. Attrition will still be terrible enough once the battle gets going and also if you need to retreat afterwards, but you should aim to get all your soldiers to the battlefield first.I just had my arse handed to me in a (until then) lovely Roman Empire game by the hordes, as I'd taken part of Persia and they decided they wanted it.
The only way I can imagine then being remotely beatable with the current doomstack is if you could get boats into the Caspian Sea so you could disembark into a fight without losing half your army to attrition. Because, while I can (and did) make a 150k doomstack, it's down to 50k by the time it gets into combat, leaving it to get eaten and spat out by the Mongol immunity stack. Give Mongols a good stream of troops flooring into Aral every now and then, but make them have to spread them out. Because I can't honestly be bothered playing again with this "lol, that side of the map dies now" mechanic in place.
That or a decision option called "Mongol Defence" which costs a huge chunk of your treasury and makes you immune to Attrition for the duration of the current war.
I beat 90k with 135k so I think 100k should fall to 150k with good generals. When I did it I loaded several times just to test it and I can't remember losing even once but I might have. Difficulty setting was hard but not very hard.150k against 100k would likely still see you lose, though. But you might wear them down to a manageable number... 30k or so... which eventually other AI factions might be able to defeat.
