Now lets take a closer look at the skills that were removed:
-Armorer
Wasn't actually removed. Instead, it was replaced with a superior, more in depth, full on crafting system that offers much more gameplay than Armorer ever did. Improvement
-Blunt / Blade
Wasn't actually removed. They were re-organized and re-classified as One Handed and Two Handed, and in the process added more combat styles than we had before. Improvement.
-Mysticism
Wasn't actually removed. The spell effects from the school of Mysticism are still in the game, they were just merged with the Alteration skill (and in the case of Soul Trap, merged with Conjuration).
-Mercantile
Wasn't actually removed. It was merged with the skill of Speechcraft, which is an appropriate choice.
So of the 8 skills that were removed, 5 of them actually weren't (Armorer, Blunt, Blade, Mysticism, Mercantile). They are all still in the game.
ADDED to the game were the returns of Enchanting and Pickpocketing, which add far more gameplay content and depth than the "run" and "jump" skills.
So in actuality, we lost only 2 skills, but those 2 skills were replaced by something better.
Armorer was changed from a repair skill with no creation to a poorly balanced creation skill with no repair. Minor gain.
Blunt/Blade was already as far "dumbed down" from any of the pre-OB games as it could get and still call it a choice. It was changed to a 1-hand vs 2-hand system, where the perks are mostly similar anyway (aside from a few like "bleed" that should have been inherent in the weapon itself, not something you had to learn how to make it do). Again, Oblivion took away a whole list and Skyrim gave a tiny sliver of it back, but it's still miles behind DF and MW. At least the perks aren't manadtory, like they were in OB.
Mysticism was distributed among the other schools of magicka, and those schools were then pared down to have less spells and effects than before, so it's roughly a net result of one skill lost overall.
How do you call "Speechcraft" plus "Mercantile" being combined NOT being the loss of a skill? It was 2, now it's 1. My outgoing and endearing Imperial couldn't care less about buying and selling, but now he's a master merchant just because he tells a good story? The cut-throat merchant is now a smooth talker. Granted, there are more important things than seperate Speechcraft and Mercantile, but don't try to say that 2 - 1 = 2.
Enchanting was put back into a useable form similar to what it was in previous games, not introduced as something new. Spellmaking was removed instead, so we STILL have no improvement overall.
I concede that adding Pickpocketing back after the long lapse since DF was a positive move.
The loss of Athletics and Acrobatics does affect some character builds, although the process of levelling them in previous games was in need of an overhaul. As usual, instead of fixing the problem, the whole game mechanic was removed.
Overall, there was a lot less lost from OB to SR than there was from MW to OB, but it's still a loss.
