I agree. The way I've balanced Berserker at my table is by having them lose a turn after rage is lost, the same thing that happens upon the loss of Haste. Perhaps they could do the same, not that it would matter with how short fights are right now. I am glad to see the subclass finally being used, but it is truly broken without that drawback.
An immediate debuff that would only impact the same fight would be better design than giving some crippling long lasting debuff that would be meaningless with BG3s rest button anyway.
They still need to address the insane burst damage though. Even before the berserker alpha strikes just ended even boss fights or the Githyanki patrol. And giving the bosses HP bloat on a harder difficulty is definitely not the answer either. It would just force the player to exploit the alpha strikes and surprise rounds which is not fun, reactive or dynamic.
