optimal use of sigma ultimate
I’m a sigma main, still pretty new to the game nevertheless. How do i use my ultimate better? I usually use it whenever theres a large group of people at a point, but I somehow always manage to leave out 2-3 people and only kill 1 person or even none. I see people saying to not use it like that and rather use it against one specific person, such as a tank or 1-2 supports that are out of position, but i also see its better to use it in bigger team fights. Whenever i ult, my team never usually follows up, so im thinking its with my usage is wrong, using it whenever theres a large group of people. Any tips please?
