Is it really my fault when my adc has 46 cs to the enemy 100, and her excuse is "i cant cs under tower"
Without any other context, it very well could be, yeah. In general if we're against an aggressive lane and you're not matching their aggression, I'm going to wind up with less CS. It's my fault I'm not perfect, but that doesn't mean you couldn't be helping me more.
You don't have any idea how many supports I get that won't even consider going near the wave except maybe to walk up, throw a Q, then walk back. Like you realize I can't CS if you don't stand with me, right? They will literally jump onto my face if you look like you won't help me.
Then you get the supports that attack and shove the wave. Can you just not? I'm trying to CS and stay safe, and you're hindering both. When we get ganked because the support shoved the wave, I know he's going to blame ME for overextending. Or, if we're losing lane and I refuse to overextend, he'll go up to their turret without me and literally take the CS.
And there are supports that will just leave you in the middle of the lane to go place a ward or something. Blitzcrank totally won't completely destroy me, and if he does it's absolutely not the support's fault in any way.
Fuck I hate low elo. Sometimes even the support MAINS do that shit.
