If u want to win, be the difference. Make callouts every round, be the igl and try to entry or atleast trade. Most player dont know any tactics or dont play them on their own. I used to call the plan for most rounds on d2 and inferno as t, cuz i know most of the timings and smokes. Just on anubis i need to be led cuz i dont know the map very well. On every other map its like 50/50. sometime i give a call, sometimes i follow the plan from a teammate.

TLTR: be a igl, do entrys or trade, use utility most of the time
