Condition Berserker is a strong, condition based build that has recently received changes which has resulted in a fairly large increase in DPS.
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.
Regardless, this build is extremely enjoyable and can perform very well on condition based encounters.
