Overall I think adding a limiting factor to barbarian is necessary. Maybe even include the threat of being downed by misusing it too much. Case and point is well, Solasta. Rage does not have any downsides there either, which leads to barbarian being a better tank at times than fighters lol. As for needing to get rid of tadpole as fast as possible, that is not entirely a thing though. Barbarians do need their counterbalance to the rage. If the threat of dying is too much for the average player, I suggest having each level of exhaustion adding a debuff to either to hit chance or movement radius.
