Vision in this game blows

The last game I played basically verified by far how I've felt about vision for a while. Usually it's not borderline gamebreaking, but this one really does it.

I was ganked by the enemy jungler 3 times within 2 minutes in top lane. Well, I guess that's not really anything that hasn't happened before, so I mean, what about it, right?

No, it was Zac and I was ganked straight from a bush. Oh well, maybe I should have had it warded. Or maybe I shouldn't have been so far up.

Oh wait. I only have one ward to use every 2 fucking minutes and I wasn't even pushed past the mid-point. But hey, I was a little far up the first death, so whatever.

Oh, the second one was literally at my tower and he jumped in from the topside bush while I had warded tri-bush. Okay. Little unfair.

Oh wait, now walking back to lane they jumped me from my fucking jungle bush - the one between the two turrets - which I couldn't fucking ward because the charge was down for another minute.

But hey, maybe I should have spent 75 gold on a control ward. 3 times. That I could only put into one bush anyway, can only have one out at a time, and I'd be giving the enemy 30 gold from my pocket basically since I have a 1 in 4 chance of warding the proper bush when the enemy has that much control over the area, not to mention I would have to walk into them to ward in the first goddamn place. So they'd just kill the goddamn ward anyway and now it's either spend another 75 gold to have an actual ward or wait around for 2 minutes never moving because I can't see shit around me.

What the fuck am I supposed to do in that situation exactly? I can be ganked from practically anywhere with only one counterplay to it and it has a 2 minute fucking cooldown. What the hell.

Thank god I was playing Swain, or it would have happened twice as often because I managed to spot them in the bushes two times with my W. Of course the other times I used it to scout it was the wrong fucking bush because, again, 25% chance of picking the right one out of the entire line-up and sometimes they're not even in the bush they're just behind a stupid ass wall, but hey, bright sides am I right?

Fuck this game's vision mechanics. Holy shit.
