There's something of a divergence when it comes to this, but I did ask officially some time ago (because of my Mk. II conversions). On the pure technical side, Dras is right: no modification of any components beyond paint scheme, no changing base sizes is spelled out in particular.
When I asked about store championships, Sullust, standard tournaments, the response for conversions was “Yeah, that should be fine as it's left up to the TO's discretion. Just clear it before the start.” I'm paraphrasing, but I can always dig up the actual reply. Still it falls perfectly in line with:
“ The head judge is the final authority on any component’s eligibility in the tournament. If a component is ruled ineligible and the player cannot locate a replacement for it, that player is disqualified from the tournament. “
So this
is as illegal as this
is as illegal as this
in the case of a premiere event. As is taking the tail of an MK II and flipping it around.
But the 1-2 fighter thing isn't as cut and dried so long as they are FFG made things. So the 1-2 fighters -say, as named squadrons for easy identification- is as interesting as question as if you may include 1 TIE advanced and 2 TIE Ln to represent Vader. All of which consist of the base components with no additional third party proxy.
Common Sense shall never reign supreme so long as people are around to rule-lawyer it into the ground with clauses to benefit themselves Still, It is an issue that can come up. Just clear it ahead of time and you're golden.
What am I missing? Why are these ships illegal? I only see a paintjob. Were some other modifications done?
