You seem to have seen so many complaints that you immediately assume every thread that is not about praising to be complaints. Read my post VERY carefully: I'm asking about possibilities to overcome the problem. Have you answered them yet?
Why, yes. Every post that's not about boot-licking Bethesda is clearly a complaint. The game has clearly no flaws and it's working all as intended.
Addressing the flaws in an open forum, which anyone has access to, is nothing but fanning the flames of hatred towards the company. No, that doesn't mean we have to turn every single topic into blind praise and ignore all the problems. All I'm saying is that you won't get the kind of support you're looking for in here, as developers hardly look at their own forums. The real issue resides in the lack of communication Bethesda has with the player base, which unfortunately we can't do much about. We can make a compilation of all the bugs and problems, but I can guarantee you they will hardly look at it. Why is that, you ask? Because no human being likes being pointed out of their mistakes, especially when it's something about they've dedicated so much time into.
The game has problems, without a doubt, but I honestly don't think pointing them out in here will attract the kind of audience you're looking for. Like I said in my previous post, you'll have to resort to the mod community to play the game as you want; fixing those details that make the difference between a polished and a rushed product. Unfortunately, console players will have to wait for a late patch to repair the damage that has already affected several people; mainly those with frame rate issues and corrupting the files.
Anyway, to answer your question, the shout seems to ignore the dual enchantment perk; meaning that you won't be able to increase the attack speed of an enchanted weapon through it. That doesn't make the shout useless, as your topic description states, since many players (myself included) don't like using enchanted weapons at all.
You wanted a complete answer, and I believe I addressed all your points. Do not take this as an aggressive post or anything of the like. On the contrary, just take it as something to think about, if at all. If I missed something, do let me know.
