I have asked for a DPS parser to be added to the game in another post not too long ago. I got a lot of pushback from the community for various reasons. The biggest being the fear of harrassment and exclusion from events due to comparisons between player DPS.
Being able to see your own DPS should be available to each player as a means to improve and to see if their play style is working or not without having to purchase thousands of dollars of additional equipment in order to do so. I think this is a no brainer.
