Yes mixed tanking can work out alright as well. There are a few fending accessories (fabled bracelet of fending / fabled earrings of fending) that give determination/skill speed/accuracy which are much more useful then parry. so if you are replacing just the parry fending accessories with strength you are gaining both some damage, and some bulk. Keep in mind that with the left side at 200 or higher, you have enough health to survive whatever you need to. (with proper cooldown management)
