Went with berserker, it seemed very useful, haven't had enough time to fully test it in pvp, but on pve i was 2 hit killing every normal mob, rendering my defense useless since they die so fast they barely land any hit, not to mention about 10k hp along with extreme high damage.
So for pve i was able too 2 hit kill all mobs at my level, using normal attack followed by 1 quick cooldown skill right after rendering them dead after it's cast, this includes lvl 40+ mobs, and possibly level 50+ as long as you stick with using high damage axes like blue color (recommended), or maybe even orange.
