How to build Warwick now?
Just started playing Warwick again after a while and wanted to know everyone's thoughts about how to build him currently such as masteries, runes, and items.

Runes: 15 AD,9 armor, 12 MR Maesteries: 18/12/0 Build: devourer, guinsoo and tank. Oneshot on ulti xD
If I had too, 
something along those lines
Skirmisher's Sabre devour BotRK Guinsoo Mobi Boots Spirit Visage Randuinn
Guinsoo's is a must have. If you have all 8 stacks (by attacking minions or so) and then ult a squishy, they will die. Having Devourer and one other on-hit item like BotRK or Wit's End also helps. Afterwards, build Tank.
Runes: AtkSpd Mark & Quint, Scaling Armor seals (WW sustain doesn't need flat) CDR glyphs (I love CDR, and go 6 constant, 3 scaling for 10% on nearly everyone)
Masteries: Fervor
Starting items (I see so many people run "recommended" and it makes me sad) Hunter's Blade + HPot. If you jungle right, you only need 1 pot. I often get 2-3 just to have spare HP for an early lvl 4 gank or in case of counter jungling.
Why: WW's sustain means that their "suggested items" are just terrible. He has so much sustain that even with machete he only needs one initial HPot for the first clear, so the talisman and refillable potion are useless and greatly slow down initial clear.
Skills: Start W and max it first. Get one point of q at level 2 for initial clear, then forget about it until the end. Just max W and E. (Obviously, max R whenever you can). Q takes too much mana. W buffs your team during ganks and fights and even when getting an initial leash. Warwick doesn't need Q to clear jungle.
Standard route: Gromp -> Blue on down. Smite on blue and red. Clear a scuttle and or gank at lvl 4, before 1st back. Most likely won't get a kill pre-6, but it keeps them on their toes. Make sure to take out each camp in the correct order: https://www.youtube.com/watch?v=PprdclQwC84 Wrong order, particularly on the chickens, will cost you an extra Hpot.
Ending: Stalkers+Devourer, BOTRK, Frozen Heart, Spirit Visage. Stalkers because you need the extra CC and WW doesn't need to use smite on monsters once he gets going. FH + SV is max CDR (with glyphs) without needing Warriors and gives you HP, Armor, & MR Devourer because WW really is all about on-hit effects. I can usually get it farmed up by ~20-25 min.
I prefer Boots of Mobility, but Merc Treads or Berserker's are viable.
If you get that far, the 6th item is always reactive for me.
Anti Magic: Wit's End
Anti AD: Randuin's
End game you are a fighter, and need both damage and tankiness.
