an alternate instance route, (which ive used like 3 times) that works well is
8-10- Rfc
10-20 SFK
20-40 Sm cath/arm (Once you get 35, you can goto zf, but i just stay at cath)
40-45 BRD
45-58- Scolo/Strat
45-58 can make the level ALOT of money, but i recommend you onyl do it if powerleveling a healing class. Ive done it Twice and made close to 1k gold off orbs boes, and trash loot/gold!
