So if you're going to shove dynamic que down our throats & fuck over Solo players by scrapping the SoloQ ladder atleast remove 4man dynamics to remove some of the pain of soloQing.
There are so many issues, & not even a single positive thing about 4man dynamics, even winning doesn't feel satifiying (similar to winning a 5v4) because you've probably contributed nothing to the win while the 4man stomps the enemy team using voice coms.
I can't imagine anyone would miss 4mans or could even provide a legitimate argument to keep them, I highly doubt there are many if any legit teams of players who only play 4man dynamic que, but there are ALOT of players who only SoloQ.
Here's a list of things 4man dynamics can do if it's removed;
split up into two duos
play 3 man
find a 5th
4 legit options, now here's a Solo players list of options if they want to avoid 4mans;
pray to the gods you don't get paired with/against a 4 man.
look up teammates to try figure out if they're a 4man then dodge if they are.
Force yourself to change how you enjoy playing the game and find dynamic partners.
None of those 3 options should have to be considered for SoloQ players.
