hows the exp rate is it fast lvling or is it hell grinding

the exp rate is pretty good till you get r2 (a term in the game which means you are wearing lvl 20 armor and weapons and you are between lvl 20-lvl 50)
but once you get to r2 youll be doin quests and thats more of a major way to lvl also you can go to dungeons which is a way lots of people lvl because dungeon monsters are way stronger than regular ones and give better exp and money so you should lvl faster another way to lvl is just farming on rappelz but to answer your question just dont try killin everythin you see it wont work except maybe if you have a stamina or stamina saver (stamina gives you more exp and jobpoints from the monsters you kill)
