Cruiser Command

We cant nerf Wraith base stats because the corvettes will truly be able to hard counter wraiths and making those 6v6 fleet engagements boring early as the fights will most likely end with who is the better corvette(with energy) and how close the engagement is to a BC.
Another upgrade that we can do is replace leech (because lets be honest, it just doesn't leech enough to make a difference unless someone gets it super early which is unlikely because of cost) with something like, oh i dont know, allow them to switch to missiles that have a better speed and are good/hull weak/shields sort of like kinetics, or make them fire 3 lazers or something, although i would write that upgrade off as a Tiered upgrade for later in the game.
Also making EMP projectile strong again to really short out the fact that a miner is faster even in upgrades game could also help (down from 50% to 25%, ....or make it an upgrade to make it cut more engines..... ^^ )

I don't think wraiths should be able to kill a miner with a similar level of upgrades unless the miner does something stupid - forcing a turbo jump is already a lot of wasted mining time, which is enough damage dealt

I would be in favor of boosting the wraith damage upgrades, since late-game the damage upgrades aren't anywhere as useful as the hull upgrades, especially once you factor in that the wraith damage is a very specific upgrade, while SS hull is a very generic upgrade
