most of the time, i quest until i can't quest anymore.
balance is maxed out, so am working on my other wizards: death is in azteca, storm in zafaria, life in cl/wintertusk, myth/ice duo in mb, and fire at the end of krok.
while she (and i) wait patiently for the xp-cap to increase, my promethean sorceress spends most of her time carting around my army of noobs... that is, she dusts off her 2-player mount and carries one of my noobs around with her, helping that wizard with (surprise!) questing. my noobs fight their own battles, but shadowsong is there to buff and heal them as needed.
other ways we like to waste time: pet training, tending her evil magma peas, noob fights (malistaire battle with no gear on), dyeing her gear hideous colours, and occasionally reagent-hunting (for whatever random piece of crafted gear she's decided is worth the time and effort to make, whether for herself or the little wizards).
none of my other wizards are crafters, and most of them got all of their stuff from shadowsong: she's the family pet-hoarder and has almost singlehandedly outfitted the army of amazingness. naturally, the others don't do very much... except for angela, my adept pyro, whom mother von takes to the arena when she's sick of azteca.
