1) Upkeeps for the Outposts, based on their level. 25 millions per week for a L250 OP sounds reasonable. Also i'd include guild fame into account. Like, if your guild get an OP in Zorai lands, but don't have enough Zorai fame, you have to pay some extra millions. Too bad Outposts are about to lose significant part of their meaning with cats being removed. Still OP upkeeps could be used as money sink for healthier economy.
2) Extra cost for all PR teleports. You get best kinds of materials in PR, gotta pay for access.
3) Some fee for buying stanzas and actions from trainers. With low level stuff coming out pretty cheap, and high level stanzas being more expensive. You get best pieces of knowledge accumulated by hominkind so far, gotta pay for it as well.
