I played a ranged caster dps in wow for the better part of a decade, and decided to try something completely new with DRG last summer. It's not as frustrating as I thought it'd be.

My skills don't have a cast time, so I can often continue my rotation while on the move. On the flipside of this, when the tank needs to move targets it can be slightly annoying trying to keep up in the middle of a critical moment in the rotation.

The only other problem that came up in the past was being on top of a boss or being in the middle of a thick of enemies that needed to be AoE'd down... and then I couldn't see the ground or anything around me because of the almost blinding spell animations going on around my character. Until I learned that I could turn down or turn off other players' spell animations, I often found I couldn't tell when I was standing in an enemy aoe circle.

It's really not as bad as I thought, even for us ground-hugging dragoons.
