Hello friends. I made a post about this on the general forums, and it wasn't very well received. I got downvoted like crazy because everybody is apparently too salty to think about the situation. Post here: http://us.battle.net/wow/en/forum/to...2876052?page=1
Anyways, here's what I'm thinking. Read this whole post before you reply, and read it thoroughly.
Right now, Tigereye Brew only gives 60% damage increase and is mainly used to enhance our Fists of Fury casts or do burst. As such, mastery is a very low valued stat. Our main focus right now is saving stacks for big FoF casts and not much else, maybe using one for Serenity every now and then.
With the coming patch, Tigereye Brew's damage is going to increase to 100%. I'm predicting that this is going to vastly increase the value of mastery. With more mastery comes more stacks. With more stacks comes more uptime. We could potentially have 100% uptime on Tigereye Brew. We wouldn't have to save it for FoF anymore, and we'd just be using it every time our buff is about to expire.
What does this mean? Consider the abilities that they nerfed by 30%. Blackout Kick, Fists of Fury, Tiger Palm, and Chi Explosion. If my prediction is correct, with the new 100% damage buff up all the time, all of those abilities are going to be doing 10% more damage than they do in 6.1. Add this on to the abilities that aren't nerfed: Storm Earth and Fire, Chi Burst, Chi Torpedo, Spinning Crane Kick, Rushing Jade Wind, Zen Sphere, Chi Wave, Invoke Xuen, Jab, Rising Sun Kick, melee swings. All of these are going to have a big benefit from the improved TEB. Essentially, TEB is going to function like Slice and Dice. It will be a huge detriment to not have it up all the time, further increasing the value of mastery.
It also looks like they want us to have more focus on Rising Sun Kick, as it didn't receive a nerf. Also, judging from the set bonuses, they clearly want us to be using RSK a lot more. A welcome change, I miss my backflip kicks being prioritized. Also, we got a buff to Tiger Strikes that gives us 15% more Multistrike.
Let me know what you guys think. I've explained my theories to a few of my friends and they think it makes sense. Remember, read this post very carefully before replying. It's a little convoluted but I laid my idea out as best I could. Also, patch notes are early and subject to change.

As for PvP, I still think it's going to be a buff. TEB won't be up all the time, but Windwalkers' only damage really comes from Hurricane Strike and Fists of Fury with 10 stacks. Those two abilities lost 30% damage, but with the new TEB they will go back up 40%. 10% additional damage on Hurricane Strikes and FoF compared to patch 6.1. It's not going to be bad at all, I'm staying optimistic.

Another edit, what the hell are those monk sets? The art team really dropped the ball there. Worst transmog patch 2k15.
