Sure, it's possible that I pick those exact spells from all those that are available. And a new player to the game on the first playthrough is supposed to know this... how?
Regardless, that makes it "possible" rather than "impossible". In fact it makes it not just possible but trivial. This is a gripe of mine, obviously. How would you know? Well, you'd have to look around the internet, or try out some of the spells. There's nothing requiring you to play on a certain difficulty, you've put that burden on yourself. While I agree with many of your sentiments in the end it's not really BioWare's fault if you don't know the spells and talents well enough to succeed at a higher difficulty.
You are right in one way, I have 3 points saved up on wynn from level 14 to 16. And I guess I have 4 more levels or so to go before I reach the end of the game. So I guess I could get those spirit spells and all of the glyphs... in time. Sadly, by the time I get these spells, I'll be almost done the game, having put up with most of the frustration by not having these spells and when I do have them all, I won't get many oppurtunities to use them.
Pretty much any encounter in the game can be won with a couple ranged, a tank with Taunt, and Force Field. You only need two spell picks to get that.
You can argue I didn't build up my campanions properly. I agree - but there's so many options, how is one supposed to know? It's not like the game's picks are awesome. And some people's advice (like getting arcane mastery because it's "so good" is just plain bad bad bad advice).
I agree, again, and the fact that BioWare seems to think being vague, ambiguous and opaque with game mechanics, spells, talents, etc. is a "feature" is highly disappointing. If I want to crank out algebraic equations to figure out the best build EVARRRR!!!! then stay out of the bloody way, make "detailed information" an option that's off by default so only those of us who care seek it out. Or put it in the manual, or a wiki, do SOMETHING for crying out loud. Regardless, I'm going to go back to your resistance to lowering the difficulty. It's up to you to learn enough about the game to succeed on a higher difficulty.
Because of the imbalance of mages vs. everything else, and the imbalance of skills within the mage tree, there is huge potential for a player to mess it up. Sure it's easy if you know what to pick... but with so many combinations being "wrong", I think that's a fault on the game's design and not so much the player. And there is no in-game respec, although I hear there's a mod for it now. Still, should have been put into the game if choosing abilities is this fragile.
I couldn't care less about a "respec" but the rest I agree with. Were I BioWare I would be examining the process this thing went through in QA and playtesting. How the hell do you manage to spend 5 years in development and come out with a game where one spell is the difference between trivial and nigh impossible battles on the hardest difficulty? It is impressive just how badly they screwed up the balance, I have to wonder if the only reason BG and BG2 didn't have "I WIN" buttons on the toolbar is because they used someone else's rules?
