Due to the shared cooldown, as well as having all shouts only on one button, switching shouts through the menu is both unnecessary and a chore. Shouts automatically get valued on a priority system, instead of using a range of them based on situation I just keep the most important one on the shout key and use that 90%+ of the time.
Having 3-5 binds and separated cooldowns for shouts would've made shouts, well, 3-5x more interesting. If I could use shift+1-3/5 or something for different shouts on separate cooldowns it'd not only give me reason to use them and also be more convenient, it'd go a long way towards making combat moderately more fun since shouts are one of the few strong points of the combat system, producing visible results solidly animated. It's a far superior experience seeing an enemy stagger from the force of a shout than just seeing a bit of blood squirt out after a sword slash with the only visible difference being in the enemy health bar. Having a small selection of default shouts would allow you to sort of customize a character in another way as well, with a sort of theme.
