It has similar light attack damage compared to a combat axe or an Eviscerator.
but:
- Less amour piercing even against flak armor. ( Eviscerators and axes has 130% damage against flask armor in max value, while thunder hammer has 75% for now, 90% after the next patch)
- Slower attack speed
- Significantly low weak spot and crit damage.
In terms of game balance, it is just underwhelming compared to other weapons. In terms of logic, it’s a HUGE HAMMER, it should be slow but needs to destroy armor even without charge, just like Eviscerators.
We can also compare it to the power maul, which has 100% damage against flak armor and 50% against Carapace armor for its light attack, and this is a crowd control weapon, the thunder hammer should at least in this level if not higher.
