Okay, I understand that, but those two phrases obviously don't mean the same thing. So if it's not feasible to simply define what "may only attack" actually means, then an acceptable alternate wording for it should be developed. It's clearly a design space that deserves a proper way of being stated.

Actually, thinking about it a little more, is there some reason why the simple, straightforward reading isn't the answer? If you can "only attack," then you can literally not do anything that isn't an attack. If some other power offers you the chance to do some other non-attack-thing instead of attacking, then in this case you just can't do that thing because it's not an attack.

There has to be an official interpretation for Gorillitroopers and Omegacon, so why isn't that also the general answer?

It's a pretty weird thought that all designers would just have to live with a design rule of "sorry, there is no possible way to prevent a unit from moving and also prevent it from using other abilities that are neither moves nor attacks." That can't really be the answer, can it?
