X-wing plays in almost the same round format as MTG. If it takes too long you don't have the time to be playing competitive games.
In the current format, yes. But there are lots of games that have tournaments where each round lasts up to 3 hours, 40K being the most obvious example.
Right which is why I don't understand how anyone can complain about X-wing competitions. I am not aware of any games that play faster. Maybe back when competitive pogs was a thing.
