I more or less use the non immediate damage/non combat oriented shouts. like whirlwind sprint for unglitching a certain thieves guild quest that has you running across roof tops. I rarely use a shout in actual combat apart from maybe marked for death and sometimes FRD. Don't wanna walk down this ridiculously tall mountain...become ethereal. Wanna go hunt a bunch of deer to lvl archery, use...aura whisper (i think thats the one :s). Point is, they are very useful to me outside of combat. iI combat, i rely on my weapons. I think my problem is 99.9% of the time in the heat of the moment of battle, I forget I even have shouts..lol
