One issue with two of the talents is the inability to crank the gun while at full ult. Steam capacitors suffers because while allowing you to keep stacks while firing, you’re not allowed to crank it to max stacks before the horde comes while at max ult which kills it’s effectiveness.
The other talent that suffers would be the attack speed talent/stacks don’t decay talent. This buff disappears when the gun fully recharges which decreases uptime, and to refresh the buff, one has to do an awkward sequence of shooting to remove some ult and then cranking it again for little uptime for the buff which kills it’s usability.
