Tony still has a whiles to go. It's not like he isn't growing rapidly. He just isn't on that level.
I've hardly seen the BE armor do much yet also. Invincible IM is such a drama comic. Even though Tony has become a beast, his enemies are actually terrosrists now. Not just douchbags bankrobbers and kidnappers. So he hasn't really had any fights where he classicly out smarts opponents with clever combinations of his tech. Which I miss.
Extremis was more interesting than Bleeding Edge. Though I like how he can morph his armor into cool bizzare forms, and the energy blade. He's showing MachineMan style feats. His so called new near unlimited power source hasn't shown much feats.
Nova smashes him.
