200 armor is 8.41% Physical Damage Reduction for a level 60 warrior and since they removed the "Get 1 AP for every point of armor you have" -ability armor is less useful now. With that said, I still use the set when tanking because I feel like having ~5+ mobs get a 8% damage reduction against you in AoE is pretty good.
Thundering Skyflare Diamond's proc is really good. I haven't crunched the numbers yet, but it is really fun to play with.
Drillborer Disk, Naglering and Heart of Wyrmthalak are excellent additions to your damage and the only thing you really have to do is to get hit or hit others. They do loads of damage as well.
Mark of the Dragon Lord is really good as Fury or Arms, but not as good as Prot since you are planning to take damage as Prot, usually. However, it isn't bad since it is a 1k absorb on a 1-minute CD.
Thunderfury, Blessed Blade of the Windseeker is really good. It's so good that it is also worth using as Fury on AoE. (Spam that Whirlwind, yo)
Now, on the topic of Versatility. I am not sure what to do with it yet. I've been running loads of dungeons and I find I survive easier when I stack it but the mobs die so much slower than if I go with my Strength gear (Which is somewhat obvious since less Strength means that each point of Versatility does less for the damage), so I take more total damage in my Versatility gear but I do not "HP-spike" as much. Versatility also isn't as good for a Warrior than for any other tank with more self-healing.
If I get a good healer while running randoms I usually go Fury-tank and spam Whirlwind/Piercing Howl. (On bosses/single-target I switch to either Protection or Arms, depending on the boss)
With all that said I'd rather take Strength over Versatility since in my full Versatility gear I only get around 20% damage reduction and Strength makes the runs more fun and a lot faster. ilvl means nothing to me, since I do nearly no PvP anymore. Experiment with some proc. items, since some of them are really broken. (I'm looking at you Ramstein's Lightning Bolts)
And ask me anything if you want to. I am always happy to talk about 60 warrior twinks.
