I know we are not yet so far but I do have a question about this :
The number of allowed units in a Fortress siege is 8 times the Fortress garrison (the basic one, Military Architecture is not accounted).
1. Fortress garisson is that of attacker I hope ? ( so with fortress 8 you can send max 225000 elite swordsman ,... so If I as defender have more troops nobody can kill me ..except if an alliance do coordinated attack ? )
2. Why a max on attacking army?? Why should we make a big army if we can not send all in one attack ?
