I have seen a lot of discussion about Epic Points rattling around the Star Destroyer Thread. Much of it seems to assume that Epic Points will follow a linear system akin to what ship cost is now.
I don't think that's the point.
Right now we know the following things.
Epic Team games have 3 Epic Points per player.
Epic Games have 5 per player.
The Transport costs 2.
The CR-90 Costs 3.
I doubt we will ever see a ship cost more or less than these two examples.
3 Points allows 1 per player.
2 Points allows 2 Per Player in Epic games or One and a 3 Point ship.
1 Point Epic ships would allow too many to be fielded at once. Nearly as many as large base ships. This seems unlikely.
4-5 Point Epic ships would be unavailable to Epic Team games, and this seems unlikely as well, because restricting an Epic ship out of part of the Epic Format seems counter-productive on the part of FFG.
I have a strong suspicion that the distinction will come from being a weapon bearing ship or an unarmed one, but we will have to wait and see. I doubt the Empire will get any Large ships at less than 3 Epic Points either way. Their Capitol ship style has always been one of enormity. Smaller ships like the Transport don't seem to fit that style.
This will allow Imperial players to have one Large powerful ship on the field per game. (2 in team games, but likely taking up 90 of each players costs.)
