Nasus setup discussion (also questions)

Hello everyone! So since the preseason, I've been wondering if the best setup has changed considerably. First of all, I have been running the mastery setup of 0/18/12 this season. While the Resolve tree will give nasus alot of what he needs, I believe the Cunning tree is another very effective strategy. I will only take time to go over the main ones. Secret stash is useful for nasus because it provides a nice extra added amount of sustain in the lane while being able to take cloth armor. Cloth 4 is my favorite start this season because of all the AD people are running and gets us closer to 20% cdr (it builds into frozen heart) I like to take intelligence mastery for the 45% cdr. It will put Fury of the Sands on a 66 second cooldown, shaving 6 extra seconds off the ultimate timer. Stormraider's Surge is the main reason I like to dip into Cunning on Nasus. While it may seem more useful on a burst champion for getting in and out, it provides a well stacked nasus basically a free move speed boost every time you Q a squishy, which will make you very sticky with or . The defensive tree is a no-brainer for the other 12 points, but I do take insight over perseverance because i can make useful teleports more often.

My personal favorite rune setup is Ad marks, armor seals, and CDR blues+quints. This allows me to have very little down time on Q in lane, missing less stacks. Surviving lane with these is not as hard as you would expect. The pros of what I have suggested are that Nasus has alot of utility he did not have access to before. I feel the tank keystones wont work on nasus because you wont be in sustained combat if you stacked correctly. The cons are that you are much less tanky, which isn't much of an issue with ADCs able to tankbust so fine anyway.

The dilemma i have run into is the proper build this season. There are a few things that have changed that we cannot overlook.

Versus + This is the main thing I have been wondering about. Before frozen heart and Trinity force was much more attractive option, but with increased frozen heart price and trinity force price, I think this is less valuable than the tweaked iceborn gauntlet. The iceborn gauntlet no longer offers ap, but now provides a total 20% cdr, a sheen proc providing more stickiness, and is a faster mini version of the other combo. The reason it bewilders me is because while the two together are a much stronger force, the iceborn is a faster version of both items combined and it can keep up with the pace of todays meta.

The other items I have been having a problem with are or The reason I wonder which one to take now is because there is a lot less opportunities to grab a visage now, and while it was a very essential part of nasus's sustain patterns mid game, the bloodthirster provides a similar benefit and it works against ad comps better. The problem with building a bloodthirster is that it has to hold off til later on or you will not be tanky enough. Visage seems like the choice I would go with but it is not easy with the amount of full ad comps now.

So my question to you is, or + and or ? Sorry if this is not neatly formatted, I do not post very often on these forums.
