Sir, mam, whichever, the point is this...
Open world RPGs are about being played as the user sees fit (mostly). Even IF (might I add... you're quite wrong in assuming you could even begin to comprehend my playing methods, as none of my builds are what you'd call "cookie cutter ideal," but I digress...) I were playing "for the sake of killing things," then that should be a viable option.
My argument here is that when you improve in doing something, you well... improve in doing it. Simultaneously improving while getting worse is hardly improving, if you could call it improving at all (Here's a great example... do you REALLY get more mileage out of one Fus Ro Dah as compared to 3 Fus? I can answer that, but you'd disagree, so feel free to experiment. Prepare for disappointment though). From the perspective of pure common sense it's already illogical. From the perspective of Skyrim, it's the reason you'd find that most people ultimately quit bothering to use shouts much, if at all. Save for a couple of shouts, most of them can't even compare to available magic spells or potions. Of those that can compare, their recharge times are so long for the variants worth actually using that bothering to use them becomes more of a hassle or a gimmick than an actual tool.
Again, PLEASE do not attempt to even start any sort of conversation with me about balance. You have absolutely no concept of imbalanced if you find anything I'm saying to be out of order. I've already given you two examples of things far and away more imbalanced that what I've talking about, so you really have no ground to stand on. I've played some of the most notoriously broken games of all time, so I have a very thorough understanding of balance (and a lack there of). Skyrim's brand of "broken" is a toddler's binky by comparison.
The Amulet of Talos? You're kidding me right? How many people do you think actually wear that thing? Not to mention... 20%? Seriously? That's a whole 8 seconds off of FORTY. It's not even worth mentioning the trivial amount it would take off of 15 seconds.
You must be new to Elder Scrolls, so I'm going to try to make this even simpler for you to comprehend.
Elder Scrolls games
are
always
BROKEN.
Always. This is not a figurative always. I mean they are literally always broken. Skyrim itself, is broken. And shouts are nowhere close to being the root of the "broken" in skyrim. You Could make shouts have a cooldown of 5 seconds and they'd still be less broken than some of the crap in Skyrim.
With that said, that's not necessarily a problem. You have the option of controlling just how broken the game is. My -NOT- making one shot kill weapons? That's me controlling the broken potential of Skyrim. My intentionally making things more difficult on myself in terms of game choices to fit my specific character's roles? I'm doing the same thing there. In fact, 5 of my characters are all part of one giant role-played family. So managing to maintain some sort of lore about them in itself is me controlling their being broken. I'm not saying everyone has to or should play that way, as my method is simply the -option- I've chosen.
What I'm suggesting still leaves you that option if you decide that it's broken. However, the reverse is not true. If I want to use my most powerful shout every 15 seconds, I can't. I'm forced to use it every 40 seconds like you enjoy it. However, if it was made 15 seconds, we can both play how we want because no one would be forcing you to use it every 15 seconds like I want to. Get it?
Open world RPG. That's Elder Scrolls. You're given a sandbox to play in as you see fit, and for the most part, everything ends up making some level of sense. But the recharge on shouts? Sorry, they just don't. Honing your voice resulting in it taking longer for you to use it is just outright silly. If somebody ever walked up to me and told me that they got better at running a 40 by "improving" a 4.4 to a 4.8, but their legs were stronger, I'd smack them in the mouth for killing my brain cells with such a stupid comment.
And no, you don't have to keep the fortify shout buff in mind. You can't even enchant with it yourself, and the whopping 20% you can achieve is an absolute joke. Furthermore, it's on items that people likely never end up actually continuing to use once almost anything marginally better comes along. The one item it's "supposed" to be on that would actually have good end-game usability is Morokei, and it's bugged/missing on that particular item.
Here's a list of far and away more broken things in Skyrim that have 15 second shouts couldn't even begin to approach
Free destruction spells (Self explanatory)
Free alteration spells (Free Mass Paralysis... yea... ain't a shout in the game that compares to that)
Free illusion (aka, free perma invisibility)
Free restoration (god mode, minus being one-shotted)
Maximized sneak/perks (invisibility, even in plain sight)
Ebony Blade-specialized characters (unkillable unless they can stop you from swinging... so since they really can't you're just unkillable)
Smithing (Make weapons that one-shot Dragons... lol, and Mehrunes Dagon thinks his Razor is something)
The list goes on
...and on
.... and on.
And you know what, it's just fine because that's just what Elder Scrolls is. A broken game with a sturdy base to let you build your own fun upon.
If shout recharge times didn't svck you could actually potentially role play something similar to what the Jarl of Windhelm had been rumored to do to the High King. That is, shout him to death. As it stands, you'd need multiple shouts to kill a "lowly" bandit, and several minutes to even do it at all. And again I say, considering you're this sort of demigod being, that's just pretty damn pathetic. Once upon a time I actually planned to make a shout-focused character, but then I realized how much of a most-of-the-time-useless gimmick they really are.
Feel free to disagree, but us agreeing to disagree is just about all that will come of this. When I'm wrong I have no problem admitting it, but I'm just not wrong here. The recharging of shouts is presently completely bassackwards.



Rather be a mage with an amazing variety of spells than a super hero....
