The idea I had was to put a dummy in the arena that parses your damage for you, instead of having to use third-party software like gamparse (which I find annoying and unreliable to use). For example, if the dummy is engaged for 10 seconds it begins to count all of the damage done to it. Once the dummy is disengaged for 10 seconds it /says total dps, time, dps by toon, max hit, min hit etc. and then resets. Does that make sense?
I would find this extremely useful, if it is possible!
