How is the topic of broken ships actually being discussed? It sounds completely stupid and completely ridiculous. FFG wants you to buy their products, hence the rule for having the actual model. Secondary to that, is that your model must be identifiable to what the ship originally was intended to be, to avoid any confusion during a game.
People modify their ships all the time. I've seen YTs with the cockpit in a completely different location. That model is completely allowed during tournament play, as long as the TO and everyone knows its a YT, and not something else. A broken ship should be treated no differently than a modified ship. As long as everyone knows it's an Xwing or a Tie fighter, or a Shuttle, or whatever the hell it started life as.
The only situation that I can really see confusion occuring with a broken model, is if someone is fielding a Tie fighter with both it's wings broken off, and a tie interceptor with both it's wings broken off. It would be very hard to tell which is which. Short of that, no one should struggle to determine what model is what.
As long as FFG is going to allow modified models, and they should allow modified models, broken models should get the same leeway as modified ones.
If a TO or an opponent gives you hell about a broken model, just tell them you modified it.
I seriously have trouble believing that anyone thinks it's ok to DQ someone because a piece broke off their ship, especially when there are any number of repaints and rebuilds of models out there that look less like the original than the original with a piece that's broken off.
Come on guys.
Where do you see that modified models are permitted in tournament play? The text from the Tournament Rules states "The size and shape of a ship model cannot be modified in any way." I take this to mean that while you can paint them, you cannot otherwise modify them or they are technically not permitted.
