Thirty years ago, we didn't have internet, affordable computers, nor consoles that could realistically play more than two players (often not even simultaneously). Multiplayer games were played on the court, or the field of a local park (or other venue depending on location). It wasn't just us as children but our parents as well. In either case, the system worked the same.
You had players of varying skill, some good, some bad. What was important is the fact that you would play on a 'team' and try to do your best. If you weren't taking it seriously, you'd be shoved aside (in some cases, literally). If your team was trying, you were trying. It wasn't a job. 99999 times out of 100000 no one was ever going to be at a level to go pro in whatever game it was. But we still tried. Your team counted on you and you counted on them.
Sometime between then and now, it became more about the individual. What do -I- get out of it? Some of us still have that old team-set mentality. Its about completing the goal with everyone pulling for everyone else. Covering their weaknesses, enhancing their strengths. The victory goes to everyone. The loot comes second. Unfortunately many of us stick to premades and statics because many don't have that team-set mentality. They're there to get it done, whomever is grouped with them is a number and a means.
But we get derided for it. People say we play the game like a job. People call us 'hardcore' (insinuating we don't have a life outside the game). Thirty years ago my dad played basketball in his late 30s early 40s. He was very good and played his best. No pro level obviously, but one of the better ones locally. It wasn't a job for him, he had a career in the military and spent alot of time with me when he wasn't working. He had a life outside that. Just like we do now with FFXIV and other MMORPGs.
We play at a high level because we like to. Its fun. Its engaging. And most importantly we want to play as a team. Its unsettling when people don't care as much about us as we do about them. That's where the disconnect and the abrasion really is. Everyone that I have raided with, done statics with, and played at the highest levels of play for the last 16 years has NEVER derided someone over parses, NEVER tried to tell someone they are wrong, NEVER booted someone simply because they weren't 'getting it'. They have kicked people from groups who are ugly to them, to those who troll the group, or make false accusations.
No, the 'elitists' you see are bad players who are JEALOUS of real players and take it out upon those who can't carry them. They KNOW they need to be carried. They HAVE to be. They will deride, insult, and vote kick anyone who they believe is standing in their way of their own carry. THOSE are the toxic players you see. Do NOT confuse them with the rest of the top tier players who simply do their thing without a word and move on. I know people in Duty Finder aren't at my level. So what? They do as they can.
If they care, they get better as much as they can. If they don't care, they turn toxic.
But don't confuse toxicity and claims of being great as actually being good at the game. One of the important facets of BEING good is working as a team. And playing the hand your dealt. And by the way, if you are one of those players that call it a job to be decent as an excuse to be less than mediocre.. you're no different than those toxic players claiming to be good. You're not just being bad at the game, you're just being a bad person. Which is far worse.
