Tactful ways to inform people that they're playing badly?

[RoyalBeef]

I did no such thing, I know plenty of Endgame players who don’t act like jerks about people in casual content not playing completely up to par. I was not calling out all Endgame players at all just the ones with bad attitudes towards those less skilled than they are.

You're trying to make an "I hate players who do XY" comment into something it's not (yes I looked it up). According to your logic every human that ever said they hated this or that is a hate filled angry person who is a threat to society and wouldprobably kill someone for cutting them in traffic or something. You're a prime example of someone that tries to make everyone walk on eggshells, because as soon as they act or talk like a normal human being, they will be dissected until you find 10 reasons why they're toxic and phobic and whatnot.
