I totally agree on Mages as a 2handed user, but everything else not so much. Blocking is overly important, but really, how is that different from Oblivion? If anything, blocking is less important in Skyrim because bashfest isn't as necessary.
I don't know if I"d say New Vegas had difficulty at all. Just make a couple poisons at a campfire, and win the game. Oblivion didn't even have a difficulty curve whatsoever. The entire game felt like you were fighting a reskinned and remeshed hp Sink. Morrowind was even more sketchy than Skyrim, particularly with NPCs. You had no idea if you were walking into a level 1 bandit cave, or a level 20 where they'll faceroll you instantly, and there generally weren't enough visual cues to give that away.
Like I said, the only thing I can agree with you on is Warlocks for 2handed characters, everything else is just silly.
In summation, every Bethesda game, and New Vegas has difficulty curve issues. It comes down to your preference, I prefer Skyrim's errors over the rest.
Right, my question being if we've improved on it or not.
The most famous difficulty curve was Oblivion's, which had leveled everything. (actually, to be fair only a handful of enemies in Oblivion continued to level with you, but the SPAWNS leveled, and they'd spawn those handful of leveled enemies 90% of the time). The result was that you'd end up having needlessly long battles against enemies that could never hope to kill you. You knew you'd win because their damage was NOT leveled, just their HP. You felt like your leveling was pointless, because while you weren't going to die, the fights took as long as ever, which was boring.
My praise of Morrowind and New Vegas was....for example you say with Morrowind, you'd see an enemy and you wouldn't know if he's a pushover or a god. Right. However, if you found out he was a god and died, you could reload, look at your inventory, and strategize how to kill him. Morrowind provided you with ample tools to kill your opponents and ample ways to approach situations, as did New Vegas. The downside to these two is that while it DOES spare you from the long pointless fights of Oblivion, some people get bored with most fights being pushovers, ALTHOUGH when you do find a tough fight, the difficulty felt right, imo. (the difficulty provided by these being you'd get into fights where you knew what to do and you knew what could finish you, and your survival depended on you NOT screwing up. For example, Divide Deathclaws in New Vegas will one-shot you, so you better get that headshot with your sniper or you're toast. The chance of success and death was equal for both you and your opponent)
With Skyrim though? Take the same scenario as Morrowind. You run into a guy on the road, you gotta fight him, you dunno if he's a god or not. He is, he kills you, you reload.
...Now what?
I think Skyrim's main weakness in difficulty curve is that it fails to provide the player with enough tools for each scenario. Two-handed vs. Mage is suicide. Mage vs. Archers is left to pray they shoot your atronach.
Some trees are very well balanced. Block has an answer to every scenario, as does archery. Several other trees however, like Two-handed and mages in general, lead you into a pot spamming frenzy, which needless to say, isn't a fun way to play the game.
All the difficulties of all Bethesda titles have upsides and downsides, but I'm asking which one people prefer. Because as things are now, I personally just get frustrated with Skyrim. If I die, I wanna die knowing I died because I failed to utilize a resource I should've or didn't play well enough. In Oblivion if I died, it's because I fought poorly. In Morrowind or New Vegas if I died, it's because I failed to utilize a tool I could've/should've/would've. In Skyrim? I die because there's just no freaking way for my two-handed character to take out that frost mage without wasting ALL of my health pots, and I don't quite enjoy dying because the shopkeeper only had 8 HP potions in stock instead of 12 that week.
