Yes, it is legal. And is easily obtainable at level 1.
It doesn't suck that bad, I mean it's easy to get money if you have access to the Item Mall, but really if you can run two Trickster accounts easily, then you could probably run four or more characters on Wonderland. Seeing how I can barely run one Trickster account and can run one character perfectly, and two so-so.
Most of the people I have seen are quite content with the game.
