Please reduce the amount of time it takes to unlock this, it seems to take a very long time. This is a pretty big issue for Eldar who don't get their dedicated AV unit automatically unlocked at T2. It is very frustrating thatin most games my opponents first vehicles will come before I've actually unlocked this upgrade and the amount of time it takes is the cause of this, I need my barracks building to be producing units and early on cannot afford to build a second barracks to begin the upgrade. Given that Las and Tankbustas both come with natural tech, I think it would be fair to reduce the unlock time of the shadow spectres upgrade, personally I would prefer making this closer to the Rangers unlock, so that it's not as hard to get AV infantry in time for early vehicles. Every Eldar player will agree with me on this, and can't see it being imba.
