Basic

This build is pretty straight foward and should be used primarily for arenas. You could use it for whatever but I recommend an aoe technology damage build for battlegrounds and warplots. You will be able to catch anyone trying to get away with Keep up the Pace and Hamstring Tear. This like most builds is heavily reliant on and landing your

Normal

(Preferably) Repeat

Rotation

You want to use between 30-70 volatility. When you do that you have a total of 76% armor penetration . From what I've seen on the internet all your passives from amps and ability trees stack with your Bio Shells debuff. All other spells will only get 36% armor penetration when between 30-70 volatility. This means you will get 36% armor penetration on 3 2 1 and 1 maybe 2 if you get lucky with crits.

Stat

Moxie > Finesse > Brutality > Grit > Insight > Tech
Moxie should be our priority since crit lets us use as much as possible. Finesse is an obvious second however is you prefer steady damage over burst damage I would go for finesse as a priority over moxie. From what I can tell strikethough pvp cap hasn't been discovered yet, but we have 3% already from amps so we should be fine. The raid cap for strikethrough is 12% so I'm assuming its significantly less.

Exosuit

With exosuit on make sure you keep up and spam you shouldn't need to use .

Survival

You shouldn't have an issue with being focused since you have heavy armor and really good tanking stance. If you are having trouble living you could sacrifice some damage amps for tanking ones or add some tanking amps with your elder gems.

Unstable

You can use anytime in you're rotation. Since this is an arena spec you will need to keep it up 100% of the time.

Elder

For your abilities I would put the last 7 into . For Amps I would suggest getting all the basic damage amps or some tanking ones. Its really up to you.
