Animal Allegiance - Pretty much useless as I seem to take down enemies quicker than animals can "come to my aid"
Aura Whisper - Probably the most useful one in terms of strategy, but I never use it
Become Ethereal - Im pretty much invincible anyway at higher levels. Also when you attack, even by accident it cancels
Call Dragon - Again at higher levels I can take down a dragon with ease before my dragon actually makes a difference. However you need to be a way in the main quest to get it so good luck getting it at lower levels
Call of Valor - And again, at higher levels I dont really need help, even on master. Maybe for fun when it gets a bit quiet when I'm exploring of whats left to be explored, Aela can be a bit boring.
Clear Skies - Who'd want to get rid of the fantastic weather effects?
Disarm - Pointless at higher levels. Okay if there are many enemies , but you can just use Ice Form to freeze everyone and they take damage
Dismay - They just come running back anyway, and as a warrior, this is pretty pointless for me
Dragonrend - I only use this when Im impatient, and I cba to wait for the dragon to actually land. I'm having a fun time exploring, boom, a dragon comes and I want to get rid of it asap. They are easy to take down anyway at high levels.
Elemental Fury - Never really used this as your weapon has to be unenchanted apparently. Unless youre an RPer (who will use shouts) or really low levelled or just dont want to wield enchanted weapons, I guess this is useful for you.
Fire Breath - Never use this, Ice Form is better
Frost Breath - Never use this either
Ice Form - I USE THIS ALL THE TIME. Mainly when there are a few enemies and I just cba to kill them so ill let the ice kill them eventually. Pretty much one of the first ones you get so its useful at every level
Kyne's Peace - Never used this but I assume the animals come back or you run into them again?
Marked for Death - Useless at high levels you can just kill them in a few hits anyway
Slow Time - I never use this but whats the point? Why would I want to wait longer to kill something?
Storm Call - Barely use this because it sometimes is laggy (PS3 btw)
Throw Voice - Useful if there are many enemies but Id rather kill them than watch them run off
Unrelenting Force - I only use this when some guy is standing on the edge of a building or cliff, I enjoy watching them fly for miles like an arrow to the adoring fans face.
Whirlwind Sprint - IOne time I used this to get to somewhere in some dungeon where I couldnt jump to. I guess its useful at low levels to run off but as a warrior I find this useless.Also when im carrying too much and im near my home I use it.
Basically, the majority of the shouts are useful at high levels. Ice Form, Dragonrend and Unrelenting Force are the 3 main ones I use all the time, in that order. The others, maybe once in a while (the other non combat ones). As a high level warrior, most of these to me are pointless now. Maybe included in some DLC we will get more "discovered" word walls and this time they will actually give you something useful to use.
Also spellmaking and enchanting need fixing (well more content), more marriage options are needed and more unique armour sets. Also more underwater content. The End.
