 The Hero Power alone is a magnitude of times better than the standard Warrior one, plus you get an extra 7 armour on top.
But even if it was something like "The first mech you play each turn has rush", it would be better.

  Tbh, late game i don't care / wouldn't care about getting KABOOM! or Micro-Squad (without rush)...

perhaps even just removing the rush for all mechs would do the trick. A small change, but one that lower the power just enough to make it less oppressive.

 I wanna refer to Brian Kibler video again. If you do that there isn't much left on Dr. Boom then just a rondom Hero Power every turn.

I wouldn't even play him then anymore and rather keep the normal Hero Power. I would go back to the old Wallet Warrior with the Grom and Alex combo.

Watch Brian Kilblers video and then you understand why it is such a strong Hero Power.

It makes it so there is no downside playing Boom becasue (in general) you dont lose your regular Hero Power. One Blast Shield makes up for 3,5x your regular Hero Power!

Also your comment does not make any sense. Other classes don't have Blast Shield...

As a Control Warrior myself I agree on Control Warrior being too strong.

I also agree with Brian Kibler that the biggest problems are the Rush Mechanic (with Warrior already having so much removal) and Blast Shield. The amount of games (against Zoo mostly) i crawled back just because of Blast Shield is just silly. The only decks Control Warrior seems to struggle against is Quest Paladin and in a lesser degree Big (Spell) Mage. 

Als this being said tho. If Control Warrior and / or Big (Spell) Mage gets nerfed some other deck and / or card will probably get too strong / oppressive and people will start complaing about that. It will allways stay like this. Game will never be 100% balanced. This does not take away that Control Warrior AND Big (Spell) Mage need a nerf.

PS Concerning Contronl Warrior (Dr. Boom) nerfs. I would go with Brian Kiblers nerfs i guess or close to it. Battlecry: Give your mechs in your hand and deck rush and remove or nerf Blast Shield or replace it so you can give a mech the Vicious Scraphound effect. If you remove the Blast Shield maybe make the Hero Power a choose effect?
