There are two things I think would be very handy to see:

Weapon speed: currently seeing just the DPS isn't really enough when you want to choose a good weapon and you rely on finding out from others whether a weapon is slow or not. Nordr jewel vs Firesquid staffs for example; the latter would appear superior as you just see the DPS, but discussed here, the former is actually better if you use skill dmg mainly.
In-game ping: I know it's in the menu, but would be great to be able to have it visible when fighting.
