Hahaha thats a lot of bros. I immediately thought of "Don't bro me if you don't know me."
Anyway. You seem to understand tanking and can add a bit more than what this guide offers. You can feel out the fight, know when to do what, and so on. That's what should happen. I dont expect this guide to be a stopping point, it should largely stable foundation to start from. So I'm glad you can take this guide use it and better yourself beyond the guide.
As for me, those skills are useless. I prefer to put my efforts into raid awareness and calling out mechanics. Keeping fracture up isn't going to push your halone combos too far behind, but the player overhead of 100% uptime may harmful. Using Shield swipe on cooldown will definitely push your halone combos behind so far that you will lose aggro. If shield swipe becomes off the global cooldown I would certainly recommend it; but in its current incarnation, given that most bosses are immune to its pacify affect, it's not even on my bar.
As for the knowing tanking thing, your comments lead me to believe that you think you can create meaningful damage wielding a sword and shield. This game is very very classical, so when you see others pushing 300+ dps and you only do 109ish, it's to be expected. Embrace that you do pitiful damage, but enhance your strengths of creating threat and taking very little damage.
