First off- I am so very happy to see Star Harpy Stewards introduced- they're the missing link that was needed to address how normal Star Harpies get around. Thank you! On another note, however, there are three elements of actual Steward behavior, two of which are actually inconsistent with their description and one of which just seems odd.
1. Stewards are explicitly stated to be 'slower' than standard Star Harpies in their description, but still have a speed of 18, equivalent to standard Star Harpies and faster than destroyers.
2. Stewards are stated to have an electromagnetic overload attack from their electrocytes at close range. Given that they aren't slower than standard Star Harpies at the moment, the fact that this is unimplemented is a mercy.
3. Stewards have self-repair capacities. Not that it explicitly says one way or another, but they don't seem to have a self-repair component, and it makes them damnably hard to kill.
Overall, though, despite any observations I make, my overriding message is just being happy the Stewards were implemented. Thank you both for your excellent work on this game, and I look forward to continued improvements!
