TA clones != SupCom FA. Please stop trying to turn this into a spring RTS. We all love our game
The reclaim values are fine, and do not need to be changed. Making it less valuable would make map control and mobility less important and turtling more effective (the opposite of what you say you want).
The Jester is a totally unique and very powerful unit... your assumption that it is a noob trap simply means that you can't use it correctly. Please don't think that because you don't like/use a unit it needs to be taken out.
Balancing mass fabs with mex is a HORRIBLE idea based on your premise. If they were balanced there would be no reason to ever expand, because you can just as easily get resources by staying in base. At the same time, current values are ok as if you MUST get more eco and all mex that are viable are claimed you can still build fab farms.
As for the AA, all tiers do their jobs and do them well.... if you can't see that I can't help you.
Again, going back to your premise of making the game more aggressive, making t3 and t4 arty more viable would make this game stupidly turtle oriented. The values set now are great, as they take a long time to build and are only viable on either large maps or in long games to break stalemates.
My two cents, take them as you will.
