I agree that that they've gone overboard with the skip/flippy stuff lately. What originally drew me to Motiv was their focus on even rolling control. I recently wanted another solid medium/heavy control piece for my sport shot league, and I ended up going with a Storm IQ Tour.
I hope that sometime in 2014 they start getting back to their roots.
Motiv was known for great "control" balls. Even when you look at earlier attempts at more of a skid flip reaction (Primal Impulse, QZ2, Raptor Attack), it was apparent their covers weren't up to par in reaction time as other companies like Storm/Roto or even Ebonite. So what you end up with is a line up of a bunch of even rolling pearls where the goal was to have skid/snap reactions. This was Motiv's "hole" up and down their line up.
Now, Motiv has the cover technology to produce a skid/snap ball much like the other bigger name companies. Once they got that, they needed to fill in their line up, which equates to about 4 balls.
Plus, Motiv releases balls differently than other companies. Instead of releasing 4-6 balls at say, BowlExpo, Motiv releases 1 ball about every 6 weeks.
Motiv has an even rolling ball at each performance category (except perhaps medium heavy with the Primal Scream, though cover changes can fix that).
