No, 5 Boxing is too expensive^^
The mage and the shaman are pretty undergeared, and im new at multiboxing so im dying often (but anyway im leveling double speed than normal - lvl 30 and 12 hrs played.. for me i think its a good time^^)
Now im trying to level to 60 with those chars - as fast as possible (ive got my lvl 70 priest leveled to 80^^)
