first of all who ever told you that gladis are liek daggers are retarded idiots and shud go play runescape...
second, the most p att u get the much more dmg ull do with all skills + auto hitting on a gladi.
third, on a low rate as you mentioned you dont have much p att obviously, but u do you have alot of hp, and its easy to get blesse body without pp from the b grade staff, so my suggestion for pvp/pve is +4/5 str and - con, dex is up to you, but dont - too much con otherwise ull have hp as low as archers/mages.
gl, i hope that helped.
