I respectfully disagree. It does indeed matter that it does not happen often. Understanding how it does happen can help us understand why it *doesn't* happen all the time.
I suggest not sitting idly by while a warrior does what he/she wants. The TFB stacks, unlike shadow orbs, don't last forever; moreover, getting five stacks requires a lot of consistent melee uptime, and a simple cc chain can make the stacks fall off.
Now, don't get me wrong, I am not at all defending TFB's damage, but let's not get carried away with reckless hyperbole. It can be a very strong offensive element when the stars and planets align and when an enemy team lets a warrior run loose. Of this I have no doubt. Mindless qq, however, doesn't move Blizzard to change game balance, nor should it. If it did, cyclone would have been dispellable since S1.
