Behaviour score is not decreasing cause it’s stucked on the same value for a bug for a lot of people and to be fair I look at my own experience with the bug, I was always 12k in 10 yrs of playing dota and since 3 weeks my communication score kept dropping and dropping till it got stucked on 6500, I don’t even know how it got to 6500 cause I won a lot of mmr this month and my games were with positive teams almost always. Real toxic people were already low behaviour score, idk why u think so many people became toxic all of a sudden to flood the bug tracker and the sub consistently every day with multiple posts about the same thing.
Shadow Fiend with Arcane Blink Abyssal Balde Refresher. Most fun I ever had in dota.
Click BKB, Arcane Blink into five heroes (it gave you faster casting speed at the time so Requiem was nearly instant cast), Abyssal onto the important target (it used to have bigger cast range and it moved you on top of the target, sort of a mini blink, perfect to deal max damage with Requiem), and insta Requiem, refresh, blink again, abyssal, Requiem again.
I’m insanely sad this does not exist in dota anymore but it was broken as fuck if played correctly… you could one shot two targets while everyone else was feared… not the only reason Abyssal and Arcane Blink got changed, they were really strong in general.
