This discussion is a bit pointless, SE already took a stance regarding DPS meters and I really doubt they will change it regardless if you agree, disagree or chose to ignore their reasons.

I understand why this would be useful (still not a necessity tho) but I doubt SE wants to deal with the "cons" it brings, this is all about money, they can still please the hardcore community without this tool while saving potential issues with the casual community (the biggest source of box sales for pretty much any game).

Now, for those who want a personal DPS meter I'd suggest making a new thread, this thread derailed long ago and I doubt they will give any consideration to that idea unless it's separated from this global DPS meter discussion.
