The frost/fire breath ones do a pitiful amount of damage, throw voice is buggy at best, and worthless at worst when you know how to sneak, become aethereal could be useful for closing on mages if getting 80% magic resist wasn't already trivial, dragonrend is nice if you don't have a bow, oh wait, except THAT won't happen because you can't play the game without a bow. What else...force shout can be fun to knock someone off a cliff, so I'll give that one amusemant points at least. kyne's peace? Sure, because I've worried about bear attacks since I was level 2... Animal companions? No thanks, my follower gets in my way enough as it is.
Shouts really add nothing at all of value to the game, so to answer your question: yes, I would without a second thought trade them for a spell crafting system.
Wow. You're a moron. Have you even TRIED using any of the shouts? Some of them are so absurdly overpowered I can barely understand how they made it past the testing process. Try Elemental Fury; It quadruples my damage for about 10 seconds. As long as I have a few stamina potions, It lets me kill anything in the game in 4 seconds, and that's WITHOUT skill-crossed smithing exploiting.
And Storm Shout. Sure, it hits your companions, but if you dont have one, it raqes a large area excessively easily. You don't even need to do anything.
How about Become Ethereal? See that Chest over there? The one behind the five frost trolls and 2 ancient dragons, with the endgame loot in it, with you at level three? Guess what, its yours now, and you didn't even get damaged in the process.
Fire breath is likewise extremely broken...at low levels. I got it at level 3, and proceded to oneshot 3 bandits at once with it, talk about ridiculously powerful.
At level 8, i killed my first giant. I Unrelenting Force'd it, then chopped at it while it spent 10 seconds getting up. On another character I couldn't kill them for another 20 levels. Talk about overpowered!
Sure, if you think you're just going to spam them all over the place like spells, it's not going to work! They're a TACTICAL BENEFIT. I don't think they should have replaced spellmaking, but I dont think that should even be an issue here. There has never been a spell to slow time, or increase your weapon speed, or call a storm, so having a spellmaking function would have essentially no impact other than a good one.
I want both, and that is NOT too much to ask.
And people who never use shouts are stupid. Unless they're RPing, then it's okay.
