CM Punk Feuds We Missed

If Punk had not left in 2014, are there any feuds or matches you'd especially like to have seen between then and now?

I'd presume an Owens feud could have been exciting. A proper run of matches against AJ sounds superb, as does a series with Joe.

AJ certainly would have been interesting.  I think Punk against this version of Roman would have meshed incredibly well too.
