Shouts are as useless as the my little pony mods on nexus.
To each his own. I play with a little more poise. Coming from MMO's, I love my crowd control and the feel of controlling the entire fight. I love gathering a ton of enemies by running through halls frantically, then backing into a corner, fus ro dah, firestorm, profit. Feel like I'm playing a better dark age of camelot.
Plus there's nothing better than shouting a group bandits off of a cliff.
