I agree with DeShin !
I have a lvl 34 Rogue/Bard and he is very good in Soloing around..
Moving march is quite usefull and Noise especially !
Well i didnt try the other buffs yet but Cleric ? i dont like to switch right in a match to cleric rod and heal myself ! Nonsense for me
The only skill which i would use is Recovery devision !
But speed is a must for me so bard
Good luck
