So, how does Riven freeze the lane? Nasus won't touch minions aside from getting lasthits/stacks. So if you go for lvl 1 punish you push the lane due to autoattacks. Same for lvl 2. You'd need a 4 minion lock to properly at your turret to properly punish Nasus, but setting it up won't work from lvl 1 on. Now, the trick is to set this up for lvl 3 without risking to get ganked at minute 2:40 - and also without getting cheesed at lvl 1 (depending on the side, if their jungler is red side he could go for a lvl 1 gank). You could obviously try and go for a hard shove lvl 1/2 so the lane pushes back to you and you immediately ward 2:38 or sth so that you lock the lane at your turret. But Nasus may go ahead and skill E and try to freeze the lane by forcing Riven to waste her Q on him so that he sacrifices HP for wave control.
Lane control is kind of hard, although Riven should be able to get it, it's certainly not an easy thing. And even if it works Nasus will just go for this new strategy and put some points in E to reset the wave. Being able to perfectly freeze the lane very early against Nasus without risking to get ganked is not that easy assuming the Nasus is decent. And even if you manage to do it their jungler might come top just to fully push and reset the lane, ensuring that Nasus will go even at 6.
Isnt pushing the wave and making it bounce back enough for this?
And, if nasus put his points in E he wont efficiently stack constantly, be weak to all-ins and be suspectible to ganks by pushing and be trash at his strongest time in midgame with a non-levelled wither. Therefore riven has done her job already.
I thought the reason why E build nasus never was a thing was due to a LOAD of problems.
