quick shot vs called shot

Maybe i am just a noob, but wouldn't called shot be more useful since it shoots and arrow 3x faster and unblockable vs call shots' 2x faster and 1 sec activation?

quick has a 1 sec recharge vs called shot 3 sec, but i think waiting 2 secs isn't that bad plus it's not an elite..

fill me in on quick shot and what makes it so elite?

I think the activation time. This makes it attack faster than Called Shot, which attacks at the normal bow attack rate.

Quick Shot has been the target of several nerfs, directly and indirectly.

The activation time, in the case of all attack skills, is a good thing, because the listed activation time is faster than a normal attack time.
