Well the main problem there is seeing this as an abuse, and not just your own ignorance. Which this is all this is :
The formation rules are clear : it doesn't say anything about the abilities listed on the officer's card. And rules include conditions of formation when they need to.
The morale rules are clear : you know when you can and when you can't activate an out-of-formation model
The movement rules are clear : you can do a full advance of 0". When you can't, or when you can't benefit from a special rule because of a 0" movement, it's included in the rule, or FAQed (like the 0" trample).
So the only reason why rubberbanding comes as a surprise, is because you haven't equated all those facts with each other. Saying this is frustrating, and that p.5 comes as an excuse to everyone who actually can figure out those interactions, well, that's just against the spirit of a competitive game. Which is, in essence, what all war-games are.
And honestly, these tricks are about all that remains from formation rules from MkI, which I loved and hoped they would have expanded upon. So I really don't see a problem. Bring snipers, or solo hunters. That's what there are there for.
