Instead of focusing on who needs a boost, I'd rather see the title go to someone who can easily be brought into a feud and can actually lift the title up, not the other way around. Let's face it: it's the IC title that needs the boost.
So slap that thing on Roman Reigns, who needs no other reason to take out Curtis Axel than The Shield is down two title belts, and Curtis Axel is a flaming bag of donkey poo. Reigns takes him out in a two minute squash match that sees Ryback half-heartedly interfere, only to be blocked by Rollins.
Now, you've got Reigns as IC champ, immediate heat with his stablemate in Ambrose, potential heat with the third wheel in the group in Rollins, and two immediate threats in Ryback and Langston. All of this builds to Ambrose Vs. Reigns, who each hold their title up after their matches to the other, practically taunting one another...at first in friendly rivalry, but eventually with more and more anger.
Net impact: Suddenly BOTH belts are seen as relevant, and you've got the makings of one hot feud that doesn't involve a main event player.
