archery? sure, thats must in like every pvp as its just 10 mins reuse, but rapid fire is not a must even if the pvp is happening in corridors/smaller areas as its very situational skill especially when he plays the damage setup SR
except that, on your place i would try to use less stuns, usually you want that only if you need to get rid of some aggro (sws/bd/tank) on your ass (but again, since you are hero and have hero zerk, even that doesnt need to bother you) and try to use double shot together with auto attack animation canceling to get some extra burst damage, but other than that, your auto attacks should be stronger than double shot
