I'm against the Skyrim system, but I think you're greatly exaggerating. It takes me about 60 hours of normal gameplay (without grinding) to get my combat skill to 100. Besides, why someone would want to grind is beyond me. You do not have to grind the combat skills in Skyrim, you just have to play normally. If you want to get them up faster, fine, but don't pretend that you HAVE to grind them in order to get them up.
I did, I reached 100 in Arhery after 80 hours on my first character and 100 in 2 hand ca 100 hours on my second character.
And I didn't just mean the combat skills, the combat skills are the easy ones to raise (excluding Smithing and Enchanting of course.).
Now getting Illusion and Restoration to 100?
I gave up on that, after 150 hours on my 2nd character I decided that I wanted to end him and play something else, I reached 60-something in Restoration.
I did not use any potions, I solely relied on using healing spells and it still didn't get up.
Hell, the armor skills are the worst, if I hadn't grinded the armor skills then I never would have gotten them to 100.
I think I've stood in front of a mudcrab hitting me for a total of an hour.
So no, I'm not exaggerating, I played Skyrim and that was a complete grindfest.
I several times decided to grind skills because it was the only way to get them up as using them normally didn't lead me anywhere.
If I hadn't cheated with player.incpcs skill for a few things and grinded the rest then I never would have gotten anything apart from Smithing and 2 hand to 100 for my warrior orc character.
So I will damn well say that I 'had to' grind the skills up. Cause I'm not gonna play for 300 hours on one character, and if that was the design then it was a horrible design choice.
[edit]
Just so there is no misunderstanding, I didn't actually "grind for 100 hours straight", I meant that it took 100 hours for me to get 2 Hand up to 100, but a good chunk of that time was spent grinding.
Actually, the combat skills were the easier one to get up to 100, it's the support skills that were even more horrid.
Ugh... The amount of times I went around Whiterun using Persuade with guards to get Speech up... Simply horrible.
