Except that everytime they have "cut" gameplay content it was for a good reason. Armor slots because of the enchanting exploit and they didn't have time to fix it. Spears because they were exploitable. Levitate because it was exploitable and also because of closed cities. There was only one skill from Morrowind that was cut and that was spears. Also, I distinctly remember people saying how useless spears were and that they hated them and now it is the greatest thing since sliced bread.
I really dont know where you get your 'facts'.
Easier ways to cut enchanting issues than removing armour slots. More likely done because of the models used in Oblivion.
As it was everyone wore a fat suit. Wouldve been worse with more bits sticking out.
Better to cure than amputate, so I dont think its much of an argument at all.
Oh, and six skills didnt make it from Morrowind to Oblvion, not only one.
The point is not spears being cut per se, the point is that the more things are removed, the smaller and less interesting game you end up with.
I miss my short blade skill, crossbows, flails.
Did I ever use any of that? No, I never did. (thats why I chose them as examples.)
Because that doesnt matter, its not the point.
Having such things in makes for a better game simply for verisimilitude and the dreaded immersion.
