[GAMEPLAY] Poppy hidden OP

I was playing Nasus in top lane and the enemy Poppy effectively glued me into the wall for way longer than the stun duration when she uses her heroic charge (think 5-6 seconds). During this time she slowly auto'd me to death against the right wall near my tower, but not in tower aggro range. I thought this issue was just me, but I heard from another person that the same thing happened to him on a wall outside of dragon which resulted in him being slowly auto'd to death over the duration of 10~ seconds.
