Just started this game about a week ago and managed to get a lvl 97 rogue but before I commit any further into this character, is there a general consensus on which class farms the best?
Take a look and see:
rouge easy use 
you can also use warrior for hp benefits haha
warriors good in farming too … but i think rogue is good at farming cuz of stealth/smokebomb skill which increase ur survival in pack size mobs and btw when ur a rogue it is easier to gain dodge % … inc power gives small boost to ur dodge%…
wizard greengarden skull build is good too you just walk around the map … mobs just die on poison. i recommend you try play all classes.
