The reason Berserker skills and weapon do so low damage is due to their large amount of percentage based increases.
Between Provoke, BerserkerRage, and Frenzy, you can easily exceed more than double damage
for everything.
BerserkerRage can reach 40%, Frenzy gives you 15%, and Provoke gives you 20%. This means that with everything active, it's possible for
every melee swing and
all damaging abilities to deal 85% more damage at a single instance. Obviously this won't happen all the time, but it is still something to consider.
Am I saying Berserker is perfect? Oh hell no. However, it
seems to be in a good place, so I'm not interested in changing too much right now. It's possible I can set BerserkerRage to cap out around 30%, or perhaps increase to 50%, but I'm not sure if it's necessary right now, I'd like to wait until we see more masters fighting before I make that call.
However,
Actually, off all Dragoon's Skills scale better than Berserker's. For Example-
Dragon's bash gets 0.875 damage per point of strength.
Berserker's bash gets 0.25 damage per point of strength.
That isn't supposed to be the case. Changing it to be the same across all warriors.

As far as the topic of left click damage is concerned, it is a given that all classes will start a bit weaker than a level 1 compared to a lvl 30 lost soul. This was the case in Bastion as well. By the time you hit lvl 10-15, you will notice things pick up considerably.
