This topic is about probably the worst thought out upgrade in the game. Stealth alloys. Stealth alloys are by far the most broken thing in this game.
Why, you ask? Well, for a few reasons. Stealth alloys can't really be countered by skill. If the enemy has about 5 escorts with stealth alloys, you're most likely if not certainly going to lose. One example of this would be in a match i had against Fosil, the guy who won the championship. I had an escort with stealth alloys and Fosil who is one of the best players in this game could do nothing about it. All you can do is spam MWJ and Beacons in the vain hope that you will detect your target. Another is the fact that this makes things like the stealth upgrade for Eldar completely inferior. While eldar are only stealthed when not moving, with stealth alloys it's all the time.
I'm just amazed people are crying about air caste and not this. If a dev is reading this, please. Just release a balance patch.
