I was thinking about that, Major Lunah and the Uhlan have similar setups. I guess I thought the Aquila didn't quite have the launch... Tubes? Terminology? But I think you're right, I hear you. Whatever the case, I'd like to see PanO keep that design.
It's always to late. It's not that they announce "windows of opportunity" in advance. It's not that anyone looks after PanO apparently. This forums are for grumbling only, and to voice frustration.
It's possible someone though it would be cool to give them large, visible, accentuated weapon to go along the line of rule of perception. On the other hand, minis are not freeze-frames in movies, and even small details tend to be thoroughly examined, so it probably wasn't needed to put those extra accents in the first place. As for "why don't they put those on everyone then if they are so small?" question, well... We don't have nanopulsers on everyone either, so...
