training? um you go around in flaris or saint morning if your like around 15-60, then you go straight to tower (in Darkon 2), after that its Azria, then Volcano. (Azria at around 70 maybe, and then Volcano at 100-120).
Class? I don't know, you should pick one that is to your liking, you can probably train 3 of your favorite classes to 120 Hero fairly quickly and then choose which one to reborn from there if you so desire. (I can't really pick between a knight and blade myself). If you want to know what I use mainly, its Blade, but don't let me influence your decision. You can buy all the good gear (greens, etc.) In Flaris.
okay, if you have anymore questions I'll try to answer them. Anyways, enjoy your stay at FFH .
