Any tips on how to mock teamers/high-kill frauds?

I just got jumped recently by FOUR players in a server. One of them had 2k kills, and one had 1k kills with incredible knowledge on Yuji's kit. Luckily, my no-job ahh got to evade them since I played asym games and cracked some ankles before. Got chased for THREE minutes. Then all of them gave up and left (at least they know chasing someone like me isn't worth it). They saw me trying to grind ULT with the Dummy and tried to jump me. The 2k kills one had Locust ULT ready and used it on me, but since they couldn't catch me sooner, I had ULT and popped it right before I was about to die to the poison effect. Could've been one of the best comebacks, but another teamer caught on and popped Sukuna's jobless domain on me with only less than 50% left.

I want to know how to easily humble frauds like them, and how to counter similar teamers in the future. Maybe some techs I missed on the characters?

btw i used mahito that time, and the teamers were:
-a yuji
-a second yuji
-a hakari (he didn't really hard team like the others, just suddenly barged in)
-a todo
-a locust guy
