@Nope-0 That might be true. I am by no means an expert in modding. Still a damage meter is something any programer can create for almost any type of mmo. Even og pso2 had one that was abandoned because sega was apparently against it (this is the first time i have ever heard that a company restricted the use of a dps tool). Toxic behavior could of course always be punished by them and is the right thing to do.
Final Fantasy 14 doesn't allow the use of DPS meters. This doesn't stop players from using them, of course, but the official stance on them prevents them from being wielded like a blunt object against players, as is so common in MMOs ("Your damage is low so we are kicking you before the final boss").
I want to be clear: I don't have a personal opinion on this. I have always used DPS meters to track my own performance while specifically turning off the tracking of other players because I don't need to stress myself out over how good someone else is at a video game. Still, POS2 is a strange game when it comes to damage output and it would be nice to have a way to measure whether or not my technique is good.
