Well, if you're going for brute force, it depends on your weapon.
For a sword you're going to want to get a total of 110 dexterity at level 55.
So whatever armor/charm you need to get to that you do.
If you're using an axe, everything goes into strength. That's all you want.
If you're planning on tanking look for
Chain or
Plate armors with lots of enhanced effect on them
to tank

Bonuses on these armors are of course strength, dexterity, and even vitality.
PM me with any further questions.
You mean.
