Ok, see if you guys understand me this time.
Basically, I know how to spot an enemy Decoy Commander. How?
Well, hover over the Commander in question, hold shift. What's different? The decloak radius of a Decoy is very small in comparison the Commander, so you can easily spot a fake.
Secondly, the radar coverage of a Commander is shown as blue when holding shift over it (sonar?), now, a Decoy has a green ring instead. I'm guessing this means the Decoy has no Sonar, which, if true, please add.
Now, Morph's an easy one, hover over the Commander and hold shift, has it got a big radar? Yes? Bingo.
I think this might be a Spring Issue, but I dunno, in any case, could do with being fixed.
I'm probably one of only ones who knows about it (noruas didn't really understand me and I had to explain it to Jools, Ansik, BD and Jim a bit) but I've battled for Decoys to actually act like Decoys, might as well finish the job.
