That's not what I mean at all. Are you being facetious?
One-word, two-word, and three-word shouts of some shouts are just CRAP. Frost Breath and Fire Breath are two great examples of that. The three-word version could be on a 20-30 second timer without a problem. Instead they are on 30-50-100 second timers. It is also, imho, more than a little weird being cut off from minor effect shouts if you use one of the big shouts, and grating to be cut off from the major effects for a couple minutes or more if you use one that is minor.
I'm not talking about using shouts as frequently as a sword. 15-40 second cooldowns for shouts that are weaker than the 3-word unrelenting force seem quite reasonable to me, even for 3-word versions, and they should be able to be mixed in with the big shouts. I think this would lead to richer and more fun gameplay to divide shouts into tiers with seperate cooldowns per tier.
I really never had a problem with cooldowns, it is
soooooo easy just to run away and wait a few hours.
I guess, in principle, I agree that the cooldowns should be adjusted for some of the weaker shouts.
But definitely not for Call Storm,Dragon, of Valor.
The first two are simply the most OP'd abilities by far in the entire game, and well the last one... they shouldn't be allowed to run around all willy-nilly either.
Yeah, I just said willy-nilly.
