Actually, it does change things. You said that you told him that Mind accessories don't do anything and when he said that it was for MP, you told him that Piety gave MP, not Mind. Your screenshot shows none of that. It's logically safe to assume that you didn't tell him Piety gave MP rather than Mind BEFORE your screenshot, as the "Give MP" reason was not said until your screenshot, so you couldn't have responded to that before being told it.
You claim that you were trying to give him information, but your screenshot only shows you responding to it with a failed vote kick attempt and a facepalm. In other words, you were kicked for acting like a jerk to them, not because you were trying to help. That makes you an example of the people who shouldn't have their paws on parsers, because you skipped the "Trying to help someone get better" and went straight for "LOLKICK".
And I said it before, a parser is not required at all to point out that a Bard should be using Dex because it's their main stat. What is required is the patience to point it out rather than jump to kick.The fact, parsers would help those players to know how far they are wrong.
Except I'm still not against parsers. I'm against people abusing them, and I think people should prove that they can handle them before asking for them. I also think people should come up with good arguments rather than "This person was wearing gear that was factually incorrect for their class and I tried to kick them instead of help them and got kicked instead". If the facts that none of their left side gear has Mind on it and their weapon has Dex and the game flat out tells you what the stats are used for are not able to convince someone that they should wear Dex accessories over Mind, a DPS number won't.being a White Knight against Parsers.
Which a parser won't do anything about. If someone's just spamming the same ability and the other's just doing 1-2-3 and ignoring positionals and both are 200+ ilvl (which means they must have at least one 210 item, which means both must have passed at least some Savage), it's a pretty safe bet that they don't care what DPS they're doing, so shoving a number at them will still get you kicked.One example: You play 1 hour each day and have to cap esoterics. you try to queue as healer to reduce queue time. Then you are pairing with 2 dps with 200+ ilvl. Your first though is -"Nice, will be a smooth run"-. Wrong. One of the dps is spamming the same ability and the other one use 1-2-3 combo without positionals. After 20 mins and a few wipes in the second boss, you try to encourage dps to do their job. They go upset because one of them or both are watching a tv-serie and you are kicked wasting your time.
That's why you should come up with real arguments why a parser should be added, like showing where people actually would be helped, rather than pointing out hopeless situations.
