People advertising they're running Parsers

[Ransu]

Actually the TOS prohibits software that modifies the games code, so it isn't "legit." They just choose not to enforce it...for now.

Parsers do not modify anything. They literally just read the text logs from the game and calculate the numbers to give you a total dps. Even if SE wanted to enforce it, there is no way they could because there's no code being injected into the game for them to detect.

and it really sucks. Coming from WoW, I was so happy to hear (what was now obviously a lie) this game had no addons. Oh well.

Technically it doesn't. There is no official support or open API like WoW and none of them are required to do content. Only the super hardcore/world first groups go out of their way to mandate any kind of raid overlays. The large majority of the playerbase doesn't care, especially considering a lot of raiders are on console where they have no access to mods anyways. I don't use any mods and I have yet found a reason to ever use them.
