ehm .. I can solo with my priest pretty easily ...

Hmmm most chars can honestly solo dungeons if theyre geared enough...cept healers >_>
Tanks arent good dps wise but they never die lol. So its a turtle kinda dungeon run.
Magic classes are pretty good for soloing anything, but they need a lot of gear, most expensive.
Gunner classes are pretty okay, but theyre squishier. High dmg output though, need pots for this.

Melee debuff like sin and ww, harder but if theyre eva build, good for soloing a lot of stuff too.
Melee sword users like Merc SB Crus and Vanq, need loaaads of pots to handle solo dungeon. I dont recommend them for efficiency.


Fastest way to level:
- Magic Tower when you can. (50? 55? ithink)
- Wanted Papers from Braden Carters NPC when its around lvl 60+
---- at 7x+ Colossus Shadowfield papers are twice as much EXP. So do those.
- Green dungeon quests when they are available =)

Theres some guide here about levelling honestly. Give those a read =)

I will try assassin and wind walker
I thought with new cap level update, those guide become out to date, sorry xD
Thanks for answers
