It's been a perfectly booked feud so far. I still wish it were happening at Wrestlemania though because the idea of WWE's two most dangerous stables (actually, aren't they the only two stables? Unless you count 3MB...) colliding on the grandest stage sounds awesome, and The Shield break-up could always happen after. But whatever. Good to know they have big(ger) plans for Wyatt since they're programming him up with Cena at Mania and since they're pushing Reigns as the next future star and know that more people will be watching Mania than any other show of the year, they probably want to showcase him to everyone with a big win instead of a loss in a tag team match.
I also love that they're holding off on any physical interaction between the two groups until possibly this last week. Also, in response to what Brad said about having three separate on-on-one matches between the six members; no, just no. Part of the appeal and aura here is that they either won't interact till the last week or possibly until the PPV itself. Not touching until the last possible moment(s) makes the match more must-see that way.
