im having a hard time deciding, i tried BLM but i died twice, i tried Warrior and THief and i didnt die at all, (not the point..) haha but anyways, witch is needed more? i like thiefs ability to get more items but i hear they are not needed so much in parties, please help! also, where is thiefs skills in windurst? sorry for all the questions. im a total newb lol ^__^
any info would be appreciated.

I don't play FFXI but usually Thief Classes have swift movements, blinking strikes (teleport to enemy to hit them) Flash movements. Nimble Body but fragile life and low mana. Fast attacking

Warriors on the other hand are usually high in armour and health, basically tankers. High damaging. But slow attacking slow movement speed. Usually gets boring.

Which is why I always play hunter class in online games =D But yeah I don't play FFXI so the above information might be pointless =p
