I’m guessing you are new to the forums, so I’m going to try to sum up some ideas for you.
1.The devs said clearly that horses will not be a thing, but will prbably be anyway since everyone is asking for horses.
2.The whole captain thing… Wouldn’t work well… You can just role play it…
3.They are working on a bunch of cool armor and weapons at the moment. You can check this or the pages 48, 49 and 50 of Paul’s Art Corner
4.The devs said that having a base would defeat the purpose of a traveling mercenary band.
5.I am pretty sure I read somewhere that the devs will add conflicts betwen houses. Not entirely sure.
6.Good idea! There should be sieges!
