Harrasing comes in many ways. Players who keep being dead on fight that actually dps or being alive matters, savage or extreme primals. Those people barely do anything, most of the time lays on the floor. Yes they do get kicked, but they keep doing it in other groups, thinking its fine. I find that insulting and harrasing the entire group. Other things that harrasses people, emote spam because they think it's fun? Sorry my blacklist is full of RMT already. People who tell me it's not fine to click 1-2 button every 10-15 seconds on tank, healer or dps but they actually do it themselves. The list is long and yes I find this harrasing, because first of all, respect the fellow player, don't think it's fine for us players to keep up with it.
Once I had a group where we had 4 underperformers, nobody (read) nobody was on pc actually, well besides the tank. If you play on ps4 you can see if the other player is actually on ps4 or not, by seing their PSN name. We had 3 enrages on sophia, this seemed fine and nobody cared and we kept going. Moral of the story, if you know you underperform, dont join, if you are in doubt, you can try. Not saying you underperform badly, because I can't judge you by not playing with you at all or whatever. However, me as a player, if I'm not confident on a job, I would certainly not join as one. This is a major problem for majority, specially people who plays BLM and keep using fire 1 instead of fire 4. You don't need a parser to understand something is wrong, same with SMN who loses stacks and never se a single dreadwyrm stance etc. However a parser can and will always have people who use them to harras others, however HARRASMENT goes both ways. You don't join on a job you know you can't perform on or barely know how to play.
But on the otherside what a personal parser could do is, show how you perform. Many gets told in a good or bad way, there should never be a bad way, there are people who are the sweetest people who even take time to google rotations, even pc players parser people who needs help, but most... yes most sadly do get offended by it and refuse to. This is a harrasment too. You respect your fellow player, the way you want to be respected. Like I said, you would mostlikely not be happy being in a group where you wipe over 20 times and be okay with it, unless if you truely are, then you should be more than happy to make a group with same mindset. People keep to forget that the players most call ''elitist, toxic etc'' are those who make guides for primals or savages and actually let us know when it will enrage or not. I never witness sophia extreme enrage ever, since it's easy to recover, but seen it too many times, even with deaths low as 2-3 max in a group. I'm not trying to lecture you or others here, you all decide how to treat others or how you want to perform, but when it comes to me, sorry, I will never ever join a group where I know I will do bad, this is my term of respect towards others.
