This has been on my mind for awhile, and seeing someone's question in the Letter from the Producer regarding add-ons made me start thinking about it again.
Right now, it seems that SE's policy regarding parsers and overlays and similar software is "don't ask, don't tell". The idea is that you, personally, can use this tool to gauge your personal DPS as the game itself doesn't give you a reliable and realistic method to do this on its own. But don't use it to disparage others. At least, that's the impression I get.
But all too often, I see people with parsers instead using them to disrupt the gaming experience. Stuff like, "Haha look at this dumb tank doing 500 DPS lololol". I can understand their frustration, truly. It's maddening to have someone not be able to pull their weight. If they don't care, that's one thing. But did you ever think maybe they don't know?
The same goes for hunt tracking software. There are tools out there there that notify people in game where a hunt has spawned. If you can see it, you can get to it and kill it first. It's like the digital equivalent of spotlighting deer. You shouldn't do it, but people still do.
With the DPS part, the concern gets divided into two camps:
1) The people who complain and call out when someone does sub-par DPS (according to their parser) because the sub-par player's lack of skill or motivation is disrespectful and detrimental to the group and their playtime. It's understandable, but I think that tools like this give some players a superiority complex.
Mind you, not everyone who uses a parser does this and I don't want to lump them all into the same category. But even if you're not going for the world first server clear, it seems like every player is seriously scrutinized and has to have some kind of high and mighty FFlogs parse in order to be considered as one of the proud few who are "worthy" enough to try Savage or Extreme Primals.
It's like people forget this is a game.
2) Then you have the people (like me) who are on console and have to ask someone to record their DPS so they can see how they're doing, and really don't know where they stand in terms of how they are contributing to the overall raid in terms of damage/support. We're flying blind. We don't know how we're doing and it's frustrating. I have a thread right now in the DPS sub forum asking how to optimize my samurai rotation because I want to squeeze every drop of damage out of it.
The developers' fix to this was to introduce SSS, but it really doesn't take into account things like the mechanics of the fight nor the contribution of other players' buffs and such.
Ideally we'd have something like an Allagan control room where we can practice fights, or portions of fights, and see how well or poorly we did. Even if AI was used to apply buffs and such much like an actual team would, it would go a long way toward helping us see what we could improve on. It has even been suggested that at the end of a dungeon or boss fight, we get individual reports on our DPS/healing contribution as a whole, like what happens in PVP. I don't know why this wasn't added in PVE.
I just feel like these kinds of add ons are becoming more and more of a requirement in order to do things that should be do-able by default (or prohibited in the case of hunts) in game. Either let us each access the same kind of information on a one-on-one basis or disallow them all.
