Can someone list all the expertise buffs that can be stacked?

I'm familiar with 6 rows of buffs from SWG, and the buffs in WoW. People ususually don't buff that much unless they have a big duel. I don't know why someone would use that much in warzones, since it can be expensive.

PvP gear puts you around 10-15% expertise.

The expertise Power up in warzones adds +15%

The Expertise pvp potion adds +15%

 

So potentialy +45% damage and -45% damage received for 20 seconds.

 

Stack that with Relic and Adrenal uses for 20 seconds of boosted crit rates and critical damage.
