Double up SP at 25+ please.

[Laughlyn]

Double SP won't be necessary, IMO.

Currently we can go 1-50 within a month already.

I took 3 months for my first class from 1-50 in the old SP system, with the current SP system i go from 1-45 in around 3 weeks, and at 40+ it's not even hard to gain a rank each reset.

That is only by doing leve quests, no grinding required.
You just need to have friends to leve-link with, that's all.

Exactly, the one i forgot, leve-linking.

Leve-link = the Shi!tz!
