for me Vit Swordsman/ Knight
and
agi archer / snipers

y vit swordsman?
high vit - high regen of hp & more effective when using pots
weapon doesnt neccessarily overupgrade just using the right elems on monsters

y agi archer?
more flee - less damage or less monsters can hit you
long range - can attack at long distance DS for fast kills
+5 hunter's bow + right elem is enough in low def monsters

Like, answer hat color, moving,disguise.

sounds like you are on a paranoid server

You're only being paranoid if it isn't true

Anyway back to topic this depends entirely on what type of server you're on.
1x = ??????
I play on 8-50 servers and there's a BIG difference even on those.
On my 50x server I agree, sniper is the best quick bot. I make a creator for Mvp hunting, and things like Orleans Gloves at Thor.
On my 8x server that's out of the question. Arrows are too expensive and make botting much less profitable, and acid bottles? Forget about it, lol.

There are other factors of course. On one server(12x) there's a %4 penalty for dying x_x And no coin trader. So dying often is NOT an option. I use LK there.

[makemecry]

for me assuming low rate server

agi monk - with self buffs + instant teleport skill

high rate server

sinx/LK -for me it's my kind of farmer in high rates xD

[Roxas]

I beleive its the Bard/Dancer class thats the fastest to lvl up cuz of the SP. If you pump in enuff INT, It wud never sit and only DS TP. You need to spend on the char tho, decent equips [I suggest +0 Hunter Set equips] and Arrow Quiver and Concentration Potions, thats all.

If you consider cheapest, Its a mage..hand down.

[n0rd]

If you talking about botting, then monk is the answer.
