Dont get me wrong. I love research. My ships always get the full program, often before they even get built.
However, there already are 3 armor, speed and damage upgrades for most ships. Adding more would make little difference in gameplay. If the opponent is stupid enough not to upgrade his fleet, then you will stomp him with your 3 upgrades any time. Now if both of you upgrade, then not even 100 levels of research in the same area will make a difference, cos your ships will always be about even in attributes.
Therefore I would like to see more variety in upgrades and add more tactical differences between vgr and hiig fleets via the upgrades I have suggested.
As for the fighter armor upgrade. I'm rather pro. Fighter class is currently useless. It needs powerups badly to raise from its role of a harmless little pest.
