You place wards when and where you need them.
Your team might need them too. You may be the jungler, but it's not just about you when it comes to warding.
Three wards in an entire game? That's terrible and there's hardly an excuse for that. Eight, I could buy in a shorter game, but three?
If someone gets a ton of cs that doesn't make them a good player.
Yeah, just like warding fifty times doesn't make you a great player.
But getting like 20 cs as a carry in a game? That speaks another story. Sure, you can have your rough games, but having low cs or low ward scores when you don't have to is an indicator that you might be able to improve.
But no, instead of improving your own game because you never make mistakes I presume, we have to bitch about the Draven.
You can make a change right now that actually matters. Bitching about the Draven is going to do literally nothing, and that's a mistake (but you never make mistakes, right?).
