For players, resetting levels to retrain as a Barbarian Berserker is definitely a tough decision. After all, many of them are already at Level 130 or 140. Once they decide to train as a Barbarian Berserker, they'll have to start from scratch.
However, according to the official website, Barbarian Berserkers of the same level will be about 30% stronger than average warriors.
In the future, leveling up will become increasingly difficult, with each level requiring a staggering amount of time, so resetting levels to re-level would be much easier. For some people, they will still choose to switch professions to Barbarian Berserker.
A Level 100 Barbarian Berserker would be comparable in strength to a Level 130 human or Beastman warrior, and they also possess many combat skills exclusive to Barbarian Berserkers.
