On your 2nd or third time around and kind of sick of gathering gear? Maybe these are "heirlooms" from your last toon...
The Alchemy chest allows you to (perhaps) explore a facet you've never fully tried. The caster chest gives access to all spells, giving you a chance to try new stuff out.

Any suggestions welcome
