Condition Berserker is a class that has receded progressively further from the spotlight. The cause lies in nerfs to and : their ability to hit more often than intended is gone.
The rotation is fairly 
Alacrity dependent and can be extremely tight if boons are lacking. This build is strong on condition based encounters, such as 
Matthias, however this is also an encounter where boons can become a bit scarce.
The main issue with this build is that you don't offer anything outside of its mediocre DPS. You offer no team support and have very limited CC.
Regardless, this build is very newcomer friendly and can be easily learnt after the 
Condition Banner Berserker.
