Opening this thread for thoughts/opinions for or against this suggestion.

Basically the idea would be a special area/zone in towns where there are target-able 'dummies" to which players can test gear sets for damage, try out macros, spells, etc.
They take damage/debuffs, won't die, and won't attack back, and there would several of them, which indicate mob levels (e.g. 20, 50, 90, etc).
And yes, this idea is taken straight out of WoW if you were curious.

Thanks!
