Im not quite sure about the percentage of how many HoQ games got streamed this season, but I feel like its around 50%, probably less tho.
So theres definetly room (and demand for you). IMO you should try streaming these games here, and if you like it, we will be lucky to have another streamer for next season :)
Yep, individual binds for players, and watrching who's got more stack/weapons or is more active to follow. Or alternatively just cg_followpowerup 1 / cg_followkiller 1. Second option is easier ofc :D
Aside from the follow power up and follow killer... I guess individually bind random buttons to follow X? (X is some number assigned to players)
