well I consider it broken I guess since I never saw a note from the devs saying they were taking it away.
They mentioned somewhere that they disabled it but not that they were taking it away, or why they disabled it.
It's a shame, really.
WELLLP with your fat wad of strat cash, you can get some fancy gear, a big army, and try to buy yourself some experience by participating in some bandit raiding.
(You can get quite a lot of cRPG exp for strat battles)
Edit: Is it against the rules to trade strat gold for cRPG gold through players because I'm sure you could work something out with a player if not.
