>>>> What about a second tier of raiding? I do quite like the mechanics behind it... fleets of ships raiding bigger settlements for better returns?
>>Yes, i like the idea but haven't really a clear thought of what are the right rewards. I don't want to make it just more of the same stuff. Also I thought of having more than one possible outcome for the existing raids, instead of just 0 or 1 crate, you might get "crate from human abbey," "crate from human castle," "crate from human village".
I would be thinking along the lines of moving the nicer stuff from tier 1 to tier 2. Getting blueprints and codex's, even if they are rare, can be quite unbalancing in the early game. As is getting usable quantities of deep bro[spoiler]nze and welded mithril. Perhaps having the weapon and armor items as uncommon items and current uncommon items as rare drops. Might not need to add additional content, just move whats there around.
I think that the items level of difficulty in creating the item should be reflected in what tier it falls in. I quite like getting masterwork ORICHALCUM longswords and full sets of platemail for my Uruk, but it does mean that I will rarely bother creating my own armors, when its so much easier to steal them.
Another thought would be to have 2 types of raids... the nautically themed longboats raiding the surface- human, elves, goblins, kobolds and perhaps a subterranean warband one pillaging the depths (dwarves, drow, ruins). Maybe have more then one target? hit a village, a small fort, etc
