This is basically an addition the already existing challenge thing.
Basically, you issue a challenge to another player (or even a public one to everyone), then someone accepts it. Up to this point, it acts like any normal challenge, with the catch the player accepting it can’t see your fleet, and it’s played out over several matches (e.g. best of 3, bo5, bo7, etc), with the ability to change fleet inbetween.
Having boX matches with the ability to change fleet inbetween, would greatly enhance the game, since it’d add the ability to react and change for both players, which the game currently lacks.
So, I can see it working like this.
1.A player sends out a challenge.
2.Someone else accepts it.
3.Both players can now watch the battle, check ending statistics, etc.
4.They can also queue a new fleet for the next round.
5. Repeat 3-4 until a victor is decided.
