X-wing shouldn't be about being like a long distance run. Long distance runs are for serious athletes pushing their bodies to the limit...x wing is a game that is meant to be fun. I feel sorry for you if you've lost sight of that.
If you want to do 3-round quick tournaments, just play local kit things and don't worry about store champs/regionals.
You're not going to see store champs/regionals be like that because their attendance is a lot higher and you need more rounds to sort it out.
And that is why more and more of these events in the future will lean toward multiple day events
