This is not a thread about viability. It's a thread about enjoying the playstyle.
To enjoy a class its a matter of good mobility,utility and survivability. Doing fancy things. And this usually means overpowering the class itself if its already in a " fine state" even tho its not as fun as it used to be.
As you said " 10 second spell reflect, charge and intercept, amazing damage, bladestorm, strong sword and board play. "This fun your talking about is also something that made warriors very strong in a perspective. Unbalanced compared to some of the other classes/specs that you could play back then. If the class isnt fun, play another class. It is a sign that uve played a class for so long that you seek extraordinary stuff to make it fun to play the class again.
Warriors will always come back and shine again, but right now other classes gets the time to experience the biggest fun in a PvP enviroment. And if its the fun that you seek, id reccommend you playing some other classes and get back to warriors when they apply some changes sooner or later.
