How would an optional, official parser be toxic?

[RuleofThree]

With regards to DPS per item level, there is currently no way to determine this save for historical data, which in and of itself will probably not always be that accurate. These first few weeks are when most raiders are in i380 crafter/normal mode gear, so they could be used as a benchmark for i380. But this will skew in the future because statics/individuals that progress faster will gear up faster (provided RNG is kind to them with drop), widening the gap between i380 and i400.

SO what you guys are telling me is that unless you are in relatively current gear, you are forced to assume your results are ok, based upon rotations and similar data? There is no hard and fast data that suggests 'ok, based on this sample in 3.0 24-man raids, it looks like a person in best gear at the time, can push out 'x' dps. Currently, in same iLevel gear, I'm pushing out 'y' dps. I wonder what I'm doing wrong for the gear and skills available to me at my level

...you are forced to guess?

I mean. I guess I could go out and put on iLevel180 gear as a dps, run a dungeon appropriate for that iLevel range, and see what I get? But again, how do I know that the number I got is accurate, if I have no sample data to base it off of?
