It really takes the shine off of any type of warrior geared towards solo exploring. Or, as Quas said, just some guy hiding on the edge of the map trying to survive after a fight.

Recuperate might give out 30-50 hp, but it has a long timer and doesn't come close to giving the healing power that old berserk did.

All in all this change has upsides and downsides. Berserk was given a slight boost, and it certainly matches well with the idea of a melee only character. On the other hand, warriors lost versatility and survivability. On the whole, I look at it as a downgrade for warriors.

Valg was the one who made the change, and it looks to me like he looked at the name and description of the skill and changed it in true "implement defecate command," style.
