Can we talk about a few balance changes to champs (NAMELY NASUS)

Hey Rioters,

I like where League is at. It's fun to play, mostly balanced, and always presenting new challenges and excitement. However, I feel like some things get overlooked. Recently I've played two matches against top lane nasus'. In one game, the summoner built full tank with 30 additional AD from items, and in the other game, he basically built full tank with 60 extra AD from items. Nasus 1) was late game critting for about 1500 dmg. Nasus 2) was late game critting for 2500 dmg.

Neither of these two champions had an IE. To me, this is just ridiculous. I understand farming kills, and leveling your Q, but when a champion can basically build full tank Items and 1 shot your carries, there is something wrong with this picture. I believe that he's not OP in the sense that he's unstoppable, I even agree with the idea of his builds in these situations, but his stacks are out of control. Can you please look into some kind of resolution to this? I feel like there are a couple of solutions that could deal with this.

1. lower the AD ratio per stack
2. put a cap on this stacks. (ie. Cassiopea)

Anytime something becomes grossly apparent as an unbalanced skill you guys usually notice this, and deal with it. No champion with only an additional 60 AD should be critical striking for 2500 damage (ESPECIALLY without an Infinity Edge) and yet walk around like an immoveable object. In both cases, he was killable but it took our entire team, and usually he'd Q one or two of us to death. The other issue with this is that no carry could kill them because of his full tank build. Even with all of the armor pen/shred in the world they still had about 3.5 - 4.5k health, and at 2500 dmg per hit, they could just out sustain even the most loaded Assassin or even off-tank ADC.
please... Please... PLEASE, look into this.

And before everyone says "just deny his farm", realize that is almost impossible. 2500 dmg crits from stacks and 60 AD is obviously grossly over-fed, but even critting for 1500+ dmg with only 30 additional AD and (NO I.E. in both cases) is still ridiculous.

Thanks for possibly reading this. Unwalked Path.
