Yoshida openly stated that he felt warrior was fine but the community objected en mass and thus WAR promptly got buffed through the ceiling. I don't really care what SE feels about it frankly, if enough of the community gets behind an idea that's not entirely unreasonable to implement, then there's a fair chance it'll actually happen, doubly so if it's not actually much work either (It's a pretty safe assumption that SE will have some form of DPS metric in the QA team's client at the very least).
Let's be realistic here, the community isn't going to rally behind a fully blown in game parser without a first step to introduce the masses to it's benefits in a watered down and easy to swallow form. However, the community does appear to be warming up to this. It's a start. I really don't see how this is so hard to understand?
Comparing it to an actual parser is completely missing the point. This isn't for you or me. This is for the overwhelming majority of people who are either unable or unwilling to run an actual parser. For these people, stepping into EX and Savage content is akin to being given a minimum speed limit on a motorway in a vehicle with no speedo. If you truly feel this is useless then there is literally no point me trying to explain anything else to you.
