well u as wizard/cleric.....bellow lvl 52 is hard kinda....
first of all if u go alone in grinding....u have no speed...and u take agro on yourself cause u have no noise...
and its kinda trouble exchanging weapons all the time to heal yourself or do the healing cycle or what ever....
bard/wizard is excelent for grinding...and for fast leveling.....if u have decent equipment u can hit multiple targets....consider this....when u are zerked u will surely kill 5 of the targets positioned at the same area....without the zerk u will probably need earth nuke and snow nuke(for
wide area dmg)... and rogue can only hit 1 mob at a time....so its kinnda hard when he is zerked too...he can only hit one target at a time...and bard can atack bunch of mobs...
the sad thing about bard/wizards is that that they intend to die much more while fighting giants and party monsters....well at least in the beggining....i have a wizard lvl 35 with npc equipment...staf iz 35+2 lol.....maybe it will be different when u are lvl 64++ with full blue +3/+4 equips...or even +5

....
but now at lvl 35 i cant atack my lvl giants...or party mobs...(well party mobs ony if i am zerked and with extreme cautiousness)
