A better idea:
A mix of plane and gunship (A gunship which has a warp drive or teleporter for about chainsaw range).
--OR--
Tac-Nukes, because Krow's original balancing intention was to kill the energy supply for Anni DDM with limited support abilities.
However, it should deal a lot of alpha damage to a few well defended targets and not kill a whole enemy base.
* It should be a bit like Archer - when the unit's energy reserves are depleted, the shield recharge stops and the weapons work not longer at full efficiency.
* Although the energy reserves could recover while it's idle.
If you spend 5000m into a unit, it shouldn't be too vulnerable to < 1000m in ANY units.
I like the idea with a shield, because most of the time you are repairing it.
* If the shield has more than 3600 hp, you can't recharge the rest with your Aegis/Aspis spam.
* But >3600 works a bit like reload-time (unless you want to send a damaged unit into battle)
Idk if you like it if it discharges on your emty base shields, but on the opposite hand, shielding your base sounds fortress-like.
