The war has been going on for a long time now, and the little guys doing all the work haven't had good job security from day 1.
Yes i'm talking about the noble constructors that we all know and love, and that we LOVE to destroy as target priority #1.
These guys should go on strike from how terrible their working conditions are.
So here is my suggestion, now that corvettes are in the game and REALLY threaten the livelihood of these guys, lets have something to make them a little more interesting.
All races should get a researchable tier 1 defense ability that allows them to research a racially specific constructor buff.
TEC: Constructors get some armor and double their current health, this helps them survive as long as they are near a healing structure.
Advent: Constructors get some shields (50% of their HP) and respawn 10%-20% faster if destroyed
Vasari: Constructors move faster and have faster turning rates (to run to safety under vasari starbase and/or phasic trap).
