90% of strat is trading goods betweens towns/fiefs/castles/etc.
I still wonder why strat is so slow? It takes ages to equip shiny army that you can lose in one good battle. That's why they all unite in huge
carebear alliances and attack only helpless targets(newbies, randomers, independant clans and others) playing without risk. Big battles itself is really fun, especially if its your own battle against equal enemy(not like 1600 shiny vs 100 unarmed) - there is a lot tactic and fun.
But that fact that you have to spend weeks to travel with trade caravan to earn good money kills all strat fun. All clans protecting their stupid s\d and you should put lot of efforts to have trade permission and good trade route. Instead of this shit i preffer steal enemies s\d penetrating in their backlines. But it risky.
You don't have to enter huge clan to participate in strat. You can be on your own, or even make your own faction, but to get success you should contact ppl, learn politics and help others you need good players to fill your roster. Its not easy but its possible.
In short words: strat is very slowpoke game, but sometimes its really fun!
