This is very interesting, and I'm glad to see people thinking about tactics in this game. I have to admit, as a horseman, I have a hard time coming up with tactics on the fly in the cliffside villages that form 90% of the maps on the official servers, so it'll be interesting to see what you guys come up with in these situations.
If I can make a suggestion, I'd like to see you guys organize a "Formation Battle Sunday Event" like we used to see in Native (they may still do it, haven't checked in a while).
Borrow a server, load up a fairly level grassy plain, and let 2 teams try tactics out against each other. It would be a great opportunity for the public to see what it's all about. When you feel that people have a good grasp of what's required, you can move to progressively more challenging maps, like one side has a hill and the other doesn't, one side gets a river, then switch, then both teams have a hill, etc. all the way up to village assaults and defenses.
Just make a forum post announcing the Event, let people apply, and select team captains for each team. The team captains can make a roster, we can all meet up, PW lock the server, and see what tactics we can get away with in cRPG world.
If you guys do this, be sure to look me up. I play a light cavalry scout hurling javelins, or a heavy cavalry man who tosses jarids into the enemy line before smashing my armored horse in and laying about with my mace.
