First one, (yes I'm going backwards) the grammar is a bit hard to understand, "...I want otherwise too) "<<<what does that mean? but I haven't really found a problem with it because i tend to adventure with my own warband so someone else should answer that.
I meant there's the dialogue option to make Lords and Kings to follow you, but not a dialogue option for you to follow them. It would be useful for the War campaign quest wich you need to be near the king's party the whole time.
Tell me what else you didn't understand and I'll try to make it clear.
Second one, maybe, tracking is meant to be able to show where other groups have gone, maybe at higher tracking levels you can choose to automatically follow them? With maybe a speed boost?
Yes, can't be something like 0 tracking, 3-4 sounds good to me. Speed boost would be nice but I would be glad already by automatically following tracks.
The last idea sounds good but think of the implications, you could follow around some large army and take pickings from the battlefield, sure you could implement that there is less loot from old battlefields, but when your right near a battle and you wait for it to finish, a rule like that wouldn't apply, if you can think of a way to apply it without people being able to cheat like that, tell us, I'll be happy to listen.
In low levels I already follow manhunters like a remora attached to a shark, letting them do the job while I kill 1 or 2 (specially now with the character bug where I was born only with a shield) just to get some loot, so I don't think it would be much trouble. When I had this idea of looting battlegrounds I didn't think of it like something very big, just thought of it like another feature for tracking and looting. You click the X and puff, a looting window menu appear and that's it. Of course you wouldn't find a Spirited Charger, Watered-Steel Scimitar and gold, just some low-end items, with a small chance of finding something good.
But now, thinking about it, to avoid this abuse specially at lower levels, as in high levels you already have good equip, maybe something like the Bandit's ambush in cities and villages could occur, but a random encounter against the Looters. And if you find it late, before the track decays, it could be already looted by the other Looters and if you're lucky you find their party and rob them.
