As a matter of fact, the siege equipment do work. What you always hear about siege is about the janky pathfinding AI, not fault in the equipment. As for perks, I believe people hate how grinding leveling gets on higher levels, not the perks themselves, which is a fair assessment. Perks give you more unique bonuses, like a chance to knock people off horses and a chance for horses in your inventory to breed, which is more than what we get from skills and proficiencies in Warband (just numbers).siege equipment (that doesn't work yet)
What I'm trying to point out with the list is that Bannerlord actually has a lot of new features, and nice ones at that. The issue people have is that many of those features are still very basic, despite having so much potential. Take the clan parties for example. Right now you can only make them. While they're roaming free, you can't tell them to not raid villages or attack caravans yet.
Sure, but in my view they're still really nice improvements that add to the enjoyment of the game. I don't think they should be ignored just because Warband had an inferior version of it. Also I forgot about that hard cap of workshops, you're right about that.Madvader did say "new and exciting", ie: a major improvement. None of these are particularly major; and are just tweaks to existing mechanics from Warband.
Also worth noting that workshops are restricted to a max in BL.
