Just had a match against a grandmaster, master, diamond and 2 plats.

You were playing flex queue. Everyone had a similar flex ranking. Fix your posts lmao.

Flex queue is very imbalanced, I think it's the lack of players that play it tbh. If you can't queue with a grand master as plat why are you able to vs them? MMR makes no sense as it does not reflect your rank.

are you playing flex? do you have more than 5 iq?

How can we form any opinion on this if we don't know what your team had?

Looks like you're not even posting on your main ... CD8 is Gold 3, so we can't even check op.gg

Without any other info - this just comes off as whining.

flex queue

2k19 and still taking flex queue seriously LOL

Okay, what about your friends? Also grand master, master, a diamond, and another plat?

Bet.
