Well generally, you should go for good spawn + killing mobs in 2-3 skills. I'd tell you go penon warriors, but yetis have good spawn either if you kill them fast. I always recommended low lvl farming, farming as much as possible and going high in 0gap. Well you WILL have low exp if you want that 4 gap, but its really up to you, what do you sacrifice for better lvling.

Anyway, if it sucks then it sucks, you'll go on better later if you have lvled over that few lvls, which are a bit slower for you.
Ps.: If you have plenty of gold, go in taxies ^^ Thats the fastest way. Prefer niya or wing(78-80) taxies.
Hope it helped.
