They're rushing to be world first because that's literally the point of a race. None of them give a single outa about a leaderboard. Heck, a good portion of players at this level don't care about FFlogs at all beyond the invaluable information it provides. Or to put it bluntly, they don't about parsing. Which is the "leaderboard" equivalent. As for them supposedly bragging, can you name five teams who were racing? Or better yet, I'll give you Kindred for free. Name four of their eight players without looking it up. Generally, when you brag about something, you want to be in the spotlighted and your name known as a result. That's kind of the whole point. So either they are all downright terrible at bragging or you're just making stuff up as you go and lumping everyone together again.
Do some brag? Of course. People brag about having all their jobs at max level. Are we going to assume everyone does that though?
You're yet again vastly overestimating what these plugins can accomplish. You or I could install any one of them right now and we'd ne nowhere close to the level of play of groups like Kindred. That doesn't mean they should be used in a world race just so we're clear but you're trying to imply they can essentially carry inexperienced or downright bad players to top 50 success. It's absolute nonsense.
We most certainly can by your logic. After all, you've decided every raider is a dirty cheaters. Therefore, it's only fair to paint all casuals with that same brush as Aravell already outlined.That EW relic? Yeah, I don't think you could pin that one solely on casual players if you tried
And before you point to the WF controversy. That is an example of one group cheating. Do others as well? Absolutely. Just like plenty of casual players love new SMN or AST while others despise them. It's almost like lumping everyone together is a bad way to argue.
