Shaman Projectile Mitigation

So far shaman has been a very fun class to play, but one thing has been a major annoyance in fights.

Ranged enemies, especially in groups. when wandering in to a cave, or doing certain required quest segments (such as the bridge in recover the past, or the nether portion in fate of the fallen) ranged enemies tend to stunlock me with no way of dealing with them, and due to shamans incredibly low defense I die too quickly to escape or kill them before they can kill me. Usually how I deal with this is finding some place to take cover, or attempting to kill the enemies before it's too late, but it becomes way too inconsistent and I'll end up dying a lot.

Some ideas I propose for this involve the existing spells. Perhaps the totem can become solid (via barriers?) or at least just deflect projectiles, when shifting while casting it (or not who knows). Another idea could be giving uproot the ability to simply destroy any projectiles it touches, though this wouldn't help much with multi-ranged enemy fights. I've not yet gotten enclosure for Aura, but according to the description I don't believe it solves the projectile issue, so perhaps Enclosure can simply deflect any projectiles coming in or out, if it doesn't do anything similar already.
