with archer buffs, war cry and duelist spirit your pretty much just like every archer, just with higher cp/hp/p def.
but using bow on gladdy would be only in extream situation, if you got rooted + got Curse of Doom on you.
and i would suggest adding +5 str - 5 con dye, since skill crit rate is based on str. if your using BW or tallum heavy, your skills got about 27%chance to crit.
