with pure str, your hp will be godly,
with the buff in warrior tree (lower damage, increase hp) your hp will even higher
with a robe, your mag def wont be that low,
and the "Mortal healling" series ( deal direct damage)
you will kill any pure int with one or two hit
at lv 20, "Over healling" deal about 600 damage directly!!
and a lv 20 nuker only has 500 hp
so, this is a bad new to pure int
