600 is pretty standard in a4 while using nearly full vit.Im not the most experienced pld ever but i pull around 850 on a dummy in full str with i200 wep.
So you should be aroungd 700-800 in most normal cases of fights while using full str.


For savage as a pld tho id either go full melded ( if you are rich) or go 3 str 2 vit sessories, that plus food should put you at the min hp required for the content assuming your healers are on there game.
