What's a good way of leveling for my maplestory character?

Um. Lvl 71 Priest. I got max bless, invincible, heal, mp eater, and tele. Then I got 1 on Dispell and 3 on Shining Ray. I'm just doing my skills my own way.. I'm gonna max Shining Ray first I think or I might put some on Holy Symbol... Right now I'm mpqing (magatia party questing) and not many people invite me to their party because I'm level 71 and they think I'm a noob. I've done it a few times though, and learned how to do everything quickly. Is there any monster I could train on or anything for more exp? When I try to train on Master Chrono and stuff they only give me .01 exp and it's so slow and boring. So any ideas or tips? D= I'm not very powerful either.
