3 things:


1. For the first 3 talents: infused hammer, third wind, piercing bolt, you actually almost never need to Hearthstone, only occasionally visit healing fountains (but a lot lot less than normal). This is actually not good because you are spending 3 talents to be topped off on Health and Mana before fights whereas if you picked 3 other CC talents you would be able to use healing fountains normally, at the expense of having to watch your mana a bit more tightly and not Thunderclapping every single minion wave.

2. You advocate Dwarf Launch (16 talent) instead of Stoneform. As a tank, the most important thing is Health and CC for your team. Throwing away a 2000hp heal for a strong escape won't help your team when you run away with low hp and they still need a tank.


3. Unstoppable Force (20 talent) is very, very situational. Unless the enemy team is stun heavy should this talent MAYBE considered. The alternate option "Hardened Shield" Negates 1000s of damage that enemies throw at you, and as a tank that is very important: soaking up the enemy team's damage for your allies. Hardened Shield definitely takes time, patience, and experience to use correctly in team fights, but is well worth it.


Overall not a bad build, but as a level 18 Muradin with over 350games, I just had to say something.
