Reiteration of Rules stating presence of low BR machines in high BR matches

Just happened to me again, another smart ass brought a biplane teammate into BR 4.0 while he flies a Mustang. The biplane fired at him, he fired back, killed his own teammate before RTB and dies.

How are these morons allowed to just come in to kill each other, contribute nothing while occupy two of the team slots?

the “humor” of seeing some useless biplane at top tier either crash, fly for 20 minutes, or spray down everyone else on the runway for the 300000000000000th time atp is about on par with some 6 year old playing a horrendous deep-fried meme track at full volume directly into your ear through some terrible phone speaker
It hasn’t been funny for a decade+, and it’s long past time to place some max br restriction on the mm for this
Tanks are functional as long as someone only brings one meme vehicle and it’s usually some low tier derp he cannon which works, but people in arb with a gladiator a 14.0 are not “farming godmode”, they’re just griefing the team
“Let people play how they want” goes out the window when the way they play actively hurts everyone else’s experience
The only person I’ve ever seen who consistently gets jet kills in a prop is smigol time, and even then he is flying a latewar prop against lower tier jets without missiles and has an extreme amount of experience

I nearly crashed doing a triple take at what I think was some sort of Yak fighter in a 9.3 match. I guess it’s popular to do that at the moment. However it’s rare enough that I don’t see an issue with it. Also had a heart attack in my Type 61 once when something completely covered in bushes shot me. I thought I was lucky bouncing chemical rounds from a TD until I shot it and it was a fucking M22
