Honestly, I much prefer the newer voting system, I never liked seeing every city be factionless, large factions had a few villages and MAYBE a castle.
Ideally I want to see a strategus with a new equipment system, I'm really sick of the current production point setup. Along with that comes the current trading system, most people spend their entire Strategus career worrying about how much S&D they have in their fief, and that's not fun. I miss the old days when I could walk into any fief and just buy whatever the fuck I wanted and have it be the same rank as what everyone else would be using, you can't do that anymore because every default item is at -2. There's a number of things that can improve this, but I'm not sure which one is the best.
Aside from all of that, there's not much else I'd change, aside from what I've posted about before. I want new ways to participate, I'm tired of it being TRADE AND WAR 2012 - 2013
I want new ways to earn gold, new ways to recruit troops, new ways to get equipment, more things to do in general. It's so repetitive and tedious at this point, GIVE ME MORE TO DO!
