Compared to Tra, it deals higher damage, which is good, except that it has less shield and runs out of energy way faster.
At the level where drones like this are used, 100 extra shield reg does not keep them alive against MF forgones and thus doesn't help them.

The energy of Katurs would be fine if they had some kind of capacitor of 10-20k, since the reg is higher than Tra.
The shields are unforgivable though. With maxed engi skills I have only 14k shields for Katur, compared to the 26k of Tra and 41k of jungle drones.
Katurs are supposed to be better than Tras, considering they are 4 techs higher. Currently they are inferior.

Thanks, added to next week's meeting agenda for discussion.

This is going to be rolled into the ongoing drone rebalance (which is mainly focused at buffing underperforming drones).
