Unfortunately I don't wanna vote either way but the fact is that your Warmog rush is just not good for Nasus, pure health doesn't work on any character that I can think of, especially if you RUSH it. Look into other utility besides pure health. Also your damage will be really bad early-game too without the Sheen/Trinity.

I'm sry but this is too squishy... U will be eaten in team fights... I think atma's and Trinity is all the damage u need. U dont have any Magic resist items... I would recomend FoN, and Banshee's against heavy CC.

All around this guide needs work. The build isn't very good, and the guide is really short. I recomend u to expand it. For example, write more about the items. Add situational items. All you wrote is basically something like " U are probably winning now, and if u havent yet, them buy this. and now this." Y ou dont really expalin why u buy them, and most importantly: What if i'm not winning? What if AP casters destroy me in team fights? U should add what items to buy in this situations and others, because going only for damage is most of the time a bad idea for a melee guy like nasus.
I hope I helped, good luck :)

edit: Another thing: You say in the end that aura's buff Nasus, so ask ur to get Starks. I think you should delete this statment, because it's just wrong... You ask your Caitlyn to get Stark's for U? Maybe u should buy the Starks to help Cait! Ur carry shouldnt be buying auras item to help the team, the team buys it to help her.

Sorry, but i dont think this is the best build. Not gonna vote though.

Very brief, and well, I just dont think the build works very well.

Nasus is suppose to played like an offtank, and not a carry.

Nasus doesn't need any damage items except for trinity force at all to do amazing damage, all he needs is farm. The other item slots are better spent on tankyness since you have to be in melee range to do damage => you will get focused.

umm... massive health and no mr? you're going to get shrededed by Hungering Strike Infected Bonesaw bioarcane barrage Madred's Bloodrazor Deathfire Grasp and the like as you inneffective hp does you no good.

I said in the comments why it was a bad guide. Very little detail, bad build choices, etc.

Its a alright guide, some spelling mistakes and very bad take on some items. Boots of swiftness is infact, a bad idea and trinity force will give you that extra boost of speed needed. Mercury treds give CC reduction which nasus doesn't like; considering hes melee. And your build becomes to squishy late game when warmogs falls off and that 1.4k health can be medicored off by alot of champions. And rushing warmogs is a bad idea for anyone (Except lee sin); and not getting GP/5 items... Just wow. Bad bad guide.
