What's with all this disdain for the game manual? Every game, except for casual things like Angry Birds is complex enough to require a manual. If you are overburdened with reading a couple of pages in a manual, it's your problem. You are seriously forcing others to sacrifice depth and immersion just because you cannot spare 5 minutes to RTFM?
Have you ever worn armor and trained with weapons? I have and thus I'm not buying your fantasies on that. It needs all three, skill, attributes like strength and derived characteristics like overall stamina. They also do not come in a magical bundle, but each one o them needs dedicated training. Someone lacking any one of these cannot expect to win against a trained opponent, however.
Additionally, Morrowind was very forgiving if it came to levelling. Even a poorly designed build could survive any level and there was really no need for powerlevelling unless you choose to raise the difficulty bar up to 100%.
If you want to argue about the future of TES series
seriously, you'll need to dispel your Skyrim fanaticism and to view the pro&cons of every game, including Skyrim's failures. You'll also need to actually start discussing things with people. Nobody questions that Skyrim was a huge financial success, but that doesn't mean that it'll be as good and long-lived as the previous games or that it's game mechanics are in any way groundbreaking.
With a skill of five, it's nearly impossible to hit anything. With a skill that low the only viable combat strategy is trying to literally click an enemy to death. But since the enemy does usually have a better chance to hit, you'll need some very good armor or even a rat will kill you easily. Overall it simply doesn't make any sense, since you can train those skills quite cheap. Acquiring money is not really a problem in this game.
Yeah, Morrowind was quite easy at higher levels, that's why they seriously beefed up the enemies in the expansions. But even then there was no need to powerlevel anything.
Oblivion's level scaling forced everyone to level efficiently, sacrificing character build options and non-combat skills. Fortunately there are mods to fix this. I wouldn't have bought Oblivion if not for mods like OOO. In fact, I didn't even bought it right from the start, because I wanted to vote with my wallet.
The same goes for Skyrim. Even while it's an awesome game in its own right, it simply doesn't feel like TES. That's why I haven't even bought the game yet and I'm playing it at my friends Xbox currently. Since I'm going to vote on it with my wallet, too, I'll buy a GOTY for maybe 20$ just because I'll need to heavily mod it to be just as enjoyable in the long term as the other TES titles.
Actually, yes, this skill unlimited training was a viable powerlevelling exploit in Morrowind, that's why it was capped to 5 training sessions per level in Oblivion.
