1st- I will agree that large ships are suffering a bit now. But I don't agree that the pass rule is the solution to bring them back. Swarms should be able to outmaneuver non swarms. Activations SHOULD be one of a swarms advantages. Isn't this really just about flotillas being cheap activations anyway..maybe there's a better way to deal with just them?
2nd- A win is NOT a win. Each match of a tournament is like an inning of a sport. They aren't separate. You don't win an inning, you just score points. You can be behind in one inning and them get ahead the next. An end game score of 6:5 is not as good a win as 10:1. You can't call them both just a win cause they are not the same.
3rd- Space is an advantage that small ships SHOULD have. Objectives bring things together. The board space provides room for more plays than just "my ships were harder and gunnier than yours".
4th- The difference between 6 and 8 obstacles is not making or breaking the tournament scene, so I don't think this needs to change until its really a problem. The objectives need to be in control of the obstacles anyway. Don't some give you 8? Close Range Intel Scan. If you want 8, play that.
