After a certain level some of my moves appear to build up something called Centering that wears off after a certain number of seconds. I think I skipped the description of this accidentally and I can't find anything online. What does Centering do and what causes it to build?

Resolve is a system to counter crowd control (CC) abilities in PvP. This meter builds up as more CC is put upon you, when it reaches a certain point this allows the player to be Resolved in his motives and he becomes immune to CC for 8 seconds. This meter is viewable by anyone. So you have to be careful to see that your opponent doesn't have a near full or full resolve meter.
This allows for heavy CC builds to be used in their full extent in PvP.
Both of them are related to critical hits. Critical Rating affects how often do you make them, Surge Rating affects how much damage do they deal if you make them.
For details, hover over Critical Chance and Critical Multiplier on your character sheet:
