I always aim for keeping 26 expertise. With current gear its possible to go well beyond that. In the transition period of waiting on drops though you can dip below.
As is my personal case atm, I'm waiting for the boots from Dreamwalker 25. So to maintain 26 expertise skill I have:
- x2 Guardian Dreadstones [+10 Expertise & +15 Stamina] = 1.22 Expertise.
- Eat the expertise food = 4.88 Expertise.
What could I gain if I didn't use those, realistically very little. Yes I loose a little stam, but due to correct placement I gain some back with bonuses.
There is something so appealing about backhanding someone across the face with a shield.
