Castle Manpower Bonuses

[SonofWinter]

Why is the attrition bonus, given to castles, used by both the besieged and the besieger. Fine, my castle, lvl. 5 in a plains province can hold 18,000 troops, does that mean that the besieging army gets this bonus to their attrition as well as my marching armies?

Seems like a bug, but I may be wrong.

Well level 5 castle requires over 10000 troops in the province during whole siege and sieger still get's minimum 2% attrition meaning it's very expensive and hard to siege huge castles already. If sieger would only get basic values at attrition (no roads, castles etc), it would mean that to get enough troops to siege a huge castle would always have something like 10% attrition at least and sieging a huge castle takes many months of time it would lead to atrocious casualties. I think it's better that you don't need a kingdom's whole manpower to siege down one huge castle and have most of them dead by attrition afterwards. Castles are strong enough as it is already.
