Druid Aquatic form could look better, i think everyone agrees.
but even more than that, and this might sound pointless, but i think you should be able to transform into it on land or in air, and even crawl around on land (with a slowed movespeed of course!)
looking retarded while swimming in the most efficient way annoys me.
swimming at the brim of the water and getting un-transformed annoys me.
not being able to transform before hitting the water for a smooth transition annoys me.
thats all...
