What's the fastest and laziest class to level, like naked, without help.

[Bboboo]

Druid. 1-29 are probably the slowest levels.

29-40 FV cliffs with an enchanter.
40-50 TD aviaks with an enchanter.

Quad to 55.
Bear pits to 60.

You now have a character that can port/buff/pl for quick plat without having to deal with camps/ec tunnel.

Also easy to move gear between alts and buy spells/items in remote places.
