My tournament experience has been that nearly every TO has asked players to submit their list via a squad builder. Given that it seems for tournaments many people are required to submit their lists for Xwing this way. Why exactly can't this be a source of a 'hard fork' of sorts?
Basically what I'm suggesting is this: FFG continues to release ships with costs that it hopes are right for casual play, For epic play, anything that isn't 100ptbattles.
You can't build an illegal squad for these games. But for anything at a regional or even store champ or more, costs of cards for tournaments become mutable and have to be checked online. Which we already have to do anyways!
no errata of wording, and nobody shows up with an incorrect list, because it has to be run through a squad builder first. A simple checker on the FFG site would accomplish this.
costs are aggressively recosted every three months to provide a solid 'churn' until it really is a completely wide open field on what you might see. At the end of a theee month period, specific ships that haven't been seen are given a 1pt bump. Ships that were seen too much are given a 1 pt decrease.
Can we just do this? Casual gaming is untouched, higher level tournament play would demand an additional check that frankly it seems like we have to do anyways already...
