I'd like to see you expand the choices for wand purchases in higher-level areas like Amrath.

I don't see any balancing problem with offering:
Resist Energy (10)
Blur (10)
Protection from Elements (10)
or even Shield (10) wands as purchasable magic.

For those of us with UMD characters, it sucks to have to buy these things off the AH all the time. These are standard buffs for nearly every quest.
