SE could do like some other games, and introduce target dummies with much higher health pools, and people can compare their results with others bases on their Time-to-Kill (TTK). Now, people who use parsers will be the first ones to figure how much HP said dummy has, and once that is done, anyone on any platform can time themselves killing said dummy, and figure out their own dps based on the TTK. SE will likely never implement a parser themselves for actual combat use, but I have complete faith that they will give us better tools in Heavensward
