CounterIntel

i think cloak could be much cooler on non-cybran units (as the combination with stealth is pretty strong).
So you would have something that's pretty strong (a unit that can't be targeted), but also easily countered by a radar.
This would create more of an intel fight by destroying enemy radars/scouts to keep cloak units hidden.

I agree, cloak is underused but we have to carefully balance this. I think Seraphim getting this would be interesting for faction flavor but they're pretty strong as is...
