New player, 0 Plat. Which class can get me to 60 the fastest?

[BarkingSpider]

Some friends of mine who already play on the server have convinced me to give p99 a shot. Since they're level 60 already, I want to get up to 55+ as soon as possible so I can start grouping and playing with them. I have zero plat, and told my friends I didn't want any free items or power leveling because I wanted to not only experience the server fresh, but also to see how well I can do for myself by the time I hit 60.

I have many different playstyles in MMOs, sometimes a healer, sometimes a caster, sometimes melee dps etc. so I don't have a preference one way or the other. I'm down to play just about anything, so long as I can make it work with absolutely zero cash and preferably in a quick time line.

Considering those things, which class would you guys suggest I make to start off as my first character on the server to get to level 60 with, as quickly as possible, with zero money for items, spells, weapons etc.?

Thanks!
