if your laning, you only need 1 ward to keep the jungler in check, and if you don't have vision don't overextend in your lane and keep tabs on the rest of the map. as for late game either stay with your team or don't facecheck bushes if your so scared of assassins. i'm not gonna explain all the ways you can avoid being jumped on by a rengar but I will say this is a bronze post.
how does one ward keep a jungler in check? lets use the hardest lane to gank top as an example. the jungler has two main entrances to your lane, river, and tribrush. so thats two spots you need to keep warded at all times to keep the jungler at bay, so that destroys your " you only need one ward" Not to mention EVERY assassin has mobility, so that opens up blast cone rout, going around krugs, going through baron pit.
Okay okay okay. we can go deeper. lets say you ward the enemies camps. so you always know which direction they went. They still have infinite options to chose from.
OH how about kayn? he can just ignore walls. how are you suppose to get around that with just 1 ward? sit under turret and never leaves because you cant have vision ever.
Not to mention how your one ward will never stop an assassin jungler. cause they will have a duskblade. so you ward. catch them once. then they come back a minute later cause you still don't have another.
Litteraly assassins are the only class to be harmed by wards. whats wrong with having more counterplay?
