I feel like you need to be at least diamond/immortal/radiant to get into decent teams :\, No one wants gold and below
I have a hard time thinking any semi-serious teams are going to accept players, that are stuck in diamond. Even hardstuck immortal 1-2's are a bit of a stretch, unless you're to the edge of being radiant/oscillate between radiant and immortal, or depending on the role as well.
I mean in reality there's no hard limit to anything, you mainly just have to be good at the game, but still it tells you something about a semi-pro/pro, if they hang in those ranks.
