Let's say you're a holly pal with Uh DK with Asphryxiate. Will you pick Fist of Justice then? No, you will pick the fear. I depends on your comp, not on the enemy one.
Misguided ppl like you shouldnt be posting here. But yeah, it easier to just copy the high rated players and then be like "omg dat swifty guy uses bladestorm, im gunna use it 2 O_O" Everyone got his own playstyle. You can't tell ppl what to use. If they want to use solace, instead of FLCD this is their desicion, not yours.
