Indeed. I will not pretend to say I know what goes on inside the mind of the man but he always came off as someone that had no real passion for the position he ended up in. There was little drive or will to innovate and the few creative surges the team did display under his leadership often ended in failure (Again, Ashran being the best example) with a complete disregard to any feedback until the damage had long been done, if at all.
Holinka seemed to have little respect for PvP in WoW and even less for the PvP community as a whole. His entire time as leader looked like he knew the exact bear minimum his team needed to achieve to keep the powers that be satisfied and never really drive those under him to push any further. He never really engaged with the community and the few interactions he did manage seemed highly forced to say the least.
In all honesty, I hope whatever role Blizzard have "promoted" him to is one he finds some actual interest in. I think it would be better for him, Blizzard and the player community that the reins of leadership are passed over to someone who actually gives a damn about the ship he is captaining.

Don't be dense. With the rate the wheels turn within Blizzard (read: very, VERY slowly), any change of leadership will not be noticeable for months. It may not even be until next expansion we see any tangible changes (assuming there is one) even if the new leader is more up to the task than Holinka was.
