Deterrence is the only ability we have as Hunters to "Shield" our selves from offensive skills/spells against us. Right? I guess not..
Almost every class has damaging Dots, and we just can't do anything about it. The bad thing is, that most of the casters can fill you with Dots instantly, so Deterrence use is just.. useless, either before or after the Dots stack on you. You must be extremely lucky to avoid instant Dots,
and if you do, they ll just spam them after the 5 precious seconds of Deterrence. All of them have some kind of shield/heal to earn some time, before
you lay on the ground. Maybe blizz could somehow improve Deterrence, so for 5 secs Dots wont hurt us..
