Wow WHAT A GREAT feedback! I am not going to Answer everything as it would grow a discussion too large for comments, but if something really bugging you, create a thread in https://heahy.com/c/warlandmarch - I created a forum there to have more structured discussion.
One thing I will probably won't change is weapon and armor types. Please try to give it some time and a few more games to get used to it and you might start liking it. I am working now on new version of page and guide so it might make it clearer to understand. What it gives is real actual counters and that gives a huge strategic depth behind a simple gameplay and controls. That also helps to create asymmetry and variability between faction units and their types.
Other things I have also thought about and it might be done in the future, especially maybe involving player a bit more with battle management. I thought about heroes but didn't think about special ability, that might be interesting.
Oh and for pacing I think maybe easiest solution would be to add additional setting for gold income before the match (now it's just spawn time), so everyone could tune what kind of match they want to play. I think I will do this in the next few updates.
