However, in the AP/AD scaling case that we have - we have completely separate defensive/offensive itemization. In many ways - this does present a lot of new problems as you've pointed out - but in many ways, it also allows us to make true glass cannon characters without simply making them feel like glass cannons because everything else's baseline damage is so high.
the problem LoL has created is given the choice of building full defense with 0 damage, in a min max tournament/high ELO environment the melee champions WILL be min maxing pure survivability since that just makes the most sense in their role.
There are many DotA champions that would never want to touch any damage but are forced to by itemization.
LoL has said "itemization for pure defense is fine! But doing no damage isn't fun... so you need to do damage when pure tank! But now you're doing damage and tanking... so we need an item for damage heroes to keep pace with you! But they'll out scale you in the end anyway..."
QSS getting an upgrade, for example, has made it so Nasus needs to be even crazier late game since every AD is going to get a cleanse, and a free massive armor shred.
Oh, also, Riven was created to beat Irelia, and Irelia was created to beat Renekton. You personally caused both the free sustain and free damage powercreep in top lane. I don't know why you always bring this up since it really doesn't look the best for you.
