This is decidedly untrue because you're comparing a stationary target against moving parts. Just look up a video of Pandaemonium (P10S) and tell me again it's the same as simply hitting a striking dummy. Not to mention, said dummy in no way teaches you how to tank or heal. If that wasn't the final nail in the coffin, they've been notoriously tuned poorly. At one point, Bard and Dancer couldn't even clear their dummy due to their damage being heavily party reliant.
Stone, Sky, Star, while not entirely useless is a very poor metric to determine if a player is competent for Savage.
Let us first define what constitutes harassment. Say you have a Dragoon who is frequently collecting damage downs or outright dying. Is it "harassment" to call out their lack of DPS even if you're still comfortably within the enrage window? I doubt many would say it is, provided you weren't being a jerk. We'll go one better and say they don't make any mechanical mistakes but they're being out-damaged by the Prange or even a geared tank. Once again, is it "harassment" to point that out and ask, "Why is your damage so low, Dragoon?" Even if you'll still clear with them, it puts far more pressure on everyone else to pick up the slack and make up for their lackluster performance. Why is that okay?If SE put in open DPS meters in the game is the same if giving them permission to shame others and openly deny people from joining groups even if they do enough DPS to beat the content because 'speed run' and other ways of discriminations.
As for the whole "speed runs" and such. I'm going to be blunt. You are not entitled to join someone's party simply because you want to. If I want to speed kill/log a specific fight and advertise it as such, why is that suddenly "discrimination" when I've made it openly apparent what my expectations are for the party I created? If you aren't looking for a speed kill, then simply find another party that suits your needs. Ironically, we already have these "discriminating" parties advertised as "barse runs". Guess what people who don't want to "barse" do? Find another party advertising weekly reclears and move on. It's really that simple.
The reason it will never be added is simply due to player coddling. They don't want players knowing how widely their damage can swing against more skilled players because that may discourage them from doing the content. They want that freestyle Samurai thinking they're a top dog contributor and not someone getting out-DPSed by the Red Mage. DPS meters only offer "grief" if they go unsupervised. It isn't as though the harassment rules suddenly don't apply. Telling someone to say, uninstall because "omg you <insert expletive> suck" is still harassment regardless if a parser is involved. In fact, just last night a friend of mine was told to "kms" (kill myself) after calling out the tank for not using cooldowns in P9S. No parser was involved yet they still managed to go that far.That is why, they said they never will add such tools, it is even prohibited to openly use them from third party programs (apps) that is why, also the gamers do not get to dictate what the devs should put into their game, it is the other way around, they can be open to suggestions, but DPS meters offer nothing but grief, and unfortunately that is the thruth.
In reality, if they ever did allow DPS meters after the first month or so when the trash takes itself out because they can't help themselves, things would mostly level out provided GMs remained thorough and consistent.
