This is so true.
While there are people that purposely go out their way to sabotage matches for their teammates, in every rank, the queue times & the SR decay in Masters & above just made me stop trying to win & decay down to 3000, a few seasons before Role Queue was implemented.
The fact that they removed SR decay for Diamond & Masters a few seasons after I gave up trying to fight the decay was a real kick in the teeth to me.
So, I just don’t even try has hard as I used to and just hang around 3000 sr on all roles & just play for fun, now.
Because I’m not going to try as hard as I once did, after the SR decay kept bring me down, multiple times, by design.
