Why is everyone saying 'bless spell' or 'vigors' ... a high lvl char will never EVER die due to ongs ... i have a lvl76 rogue and with x-bow extreme i dont needto pot EVER ... even when I was fighting a pt giant and many normal pts

First time I need pots is at Yeti, and even that is while using extreme, so please do not say that a wizz would ever die due to Ong since they have the same health as I have when I have the extreme but they still have full def (while I have -40% phy def)
And yes, a wizz is probably better than a rogue because of MASSIVE AoE damage, I mean common one hitting and entire swarm of pt ongs in one attack is just ... sick
