In reality Punk is not winning that IC title. Punk as IC champion does nothing beneficial for him at this stage in his career. He is one of the elite in wwe and needs to continue doing his big time things.
And why would you want to waste time trying to elevate the value of IC title now? Its not gonna work if the title is not being booked on TV regularly and defended consistently. Most of all is there even a midcard divsiion of wrestlers existed that wants to compete for the titles? The IC title has been shitted on for many years and a single feud aint gonna bring the "prestige" back easily.
Unify the IC with the US title. Get Rid of the so called world heavyweight championship. And then the IC title would be in positioned to bring its prestigious back.
I agree that the belts need to be unified, but I think the midcard belts need to be built up BEFORE the unification happens. That way, when the World Heavyweight Title is taken out of the picture, whoever's left standing as the unified midcard champion, whether that be Punk, or if Punk were to job the IC Title to someone like Dean Ambrose, that person already be established
And even if Punk is "too good" for the IC belt, the person who holds it and builds the belt up during this period should still be someone who the casual fan sees as "important". Maybe someone like Christian, Ziggler, or Miz, or give it to Sheamus when he comes back.
