What are you're new rune builds for Nasus?

What kind of ideas have people crafted up so far? I've been messing around with the new runes a little bit, and based on what I know of the abilities so far it seems like it could be an indirect nerf maybe? I usually run 30% scaling CDR, or 15% flat + 5% from Intelligence mastery with Nasus, and I can't even get close to that much with the new runes.

The most I'm able to get so far is 10% from Transcendence in sorcery, and 5% Cosmic insight from Inspiration. The Transcendence only comes into effect after level 10 as well. Cosmic Insight also gives you 5% max reduction as well as cool downs on items, and summoner abilities.

I rolled with Sorcery as primary with Phase Rush.

My minor Runes...

The Ultimate Hat - which seems OP with Nasus. Reduces CD on Ult by 5% and 2% more for a total of 5 stacks each time it goes on Cool down. (Is the CDR here accounted differently than your overall CDR? Do they stack? If I have 40% CDR and 5 stacks of this which will give me 15% CDR on ult will that make it 55% reduction or will it still be 45%?)

Transcendence -- 10% flat CDR at level 10. Not sure how I feel about that. Each percent of CDR exceeding the cap gives you bonus damage and ap. Something Nasus doesn't really need but I guess its pretty neat.

Waterwalking -- Bonus movement speed and damage/ap in river.

Secondary I took Inspiration

Cosmic Insight -- 5% CDR, 5% Max CDR, 5% item CDR, 5% Summoner CDR.

Magical Footware - Free boot at 10 minutes, cannot buy boots before then and they give additional MS.

There are a lot of cool abilities in the tank tree too but.... no CDR sadly. And the Sorcery tree gives plenty of power to his ult and MS buffs to help him from being kited.

Thoughts?
