I see no problem with them, if you're on PC just download one and run it but be respectful and if people harass you report them and leave the run. I mean a large majority of PC players are using them now anyways and SE doesn't care unless you're abusing it or harassing people at that point those people can get a ban.

Some of our groups run parsers to improve themselves and honestly our rule is never say anything unless someone asks how they're doing and some of our ps4 players are always asking PC people to tell them because they don't have the option of one.
