Lets theorycraft for a second about Cybran acu cloak cost being reduced to the same amount as an Aeon heavy shield. What would be the balance issue?
1. Cloak + stealth is OP! Well not really. An omni would still be cheaper and costs less energy to keep online.
2. You would not be able to snipe if acu is out of omni range. Ok but that means the acu is not on the front line using the cloak.
3. You would just be able to strut around without being countered until omni is made. Cloak costs 3000 energy to stay active. Any usage before getting a t3 power gen dedicated to it alone would mean temporary cloak and the need for lots of storage. Since this means that an acu without laser would only be effective with overcharge. That already gates the usage substantially.
The point is that with the energy requirements of cloak, the usage and effectiveness would scale in the mid game in proportion to how much energy overflow the player makes. The main reason to get it would be the HP. The cloak is just an extra.
