Bloodmage HP overflow improvements

When going from map to hideout and back to map (to clear full inventory), I think our Life overflow should persist (sort of like if I'm low on life and have to use the well). It kind of feels bad that it goes away.

Maybe to prevent abuse, you have to return to the same zone, so you can't overflow health in acts, then go fight a pinnacle boss with the overflow.

Map > hideout > same map = keep overflow
Act 1 Clearfell > Clearfell Encampment > Clearfell = keep overflow
Act 1 Clearfell > Hideout > map/breachstone = DON'T keep overflow

Something like that...
