Apaches are loud, so I can't see how it can sneak up without the MRLS knowing its presence. And no, its not screwed if it has friendlies around (which in most cases, it does).
Orcas and Apaches actually do need a nerf in fact, and I thought its the most prominent one. They're way to versatile: unstoppable rushes, map control, covering beacons, infantry transport, they can do everything very well except sneaking.
