So far, with what we know about hunters in WoD, we are getting a major buff to soloing again. MoP gave us an awesome mend pet glyph, and now WoD will give us With or Without You, essentially turning our BM pet into a dps/tank hybrid, making him do the same amount of damage roughly in tenacity as in ferocity. At the moment with 576 ilvl, my pet does roughly 210k dps, without raid buffs and some procs, lets say 150k dps to be expected while soloing.
Our pet alone, could kill a boss with 54 million health in 6 minutes. That is without us shooting a single shot.
That pretty much means, our pet can solo any pre MoP 10m boss, and at least half of the 25m bosses.
Now add in our own damage with that, and you'll be well over 100m damage over 6 minutes. Meaning we would have the dps to solo nearly all MoP 10m bosses prior to ToT (where mechanics allow of course).
Now i know after the squish all these numbers will change, but if blizz does the balancing of the squish to come out the same as now, im sure a raid ready WoD Hunter can solo a lot of MoP without many issues.
As a hunter just now starting in the solo scene, I would expect to see me posting some nice kill videos in WoD.
I realize most don't care about this, but I figured I would type out my thoughts and share.
Btw, maybe stacking STAM will be best for soloing next xpac with our super pets. (imagine our pets now with 1 million health, and mend pet/spirit mend)
