I think the one big reason the equivalent of mods could come to ships is $$$. CG monetized Mods with Mods 2.0 and eventually they’ll do the same thing with ships.
Plus (for those that love ships) when you get to end game do you want everyone to have the same maxed out ships with the same exact stats? End game the equivalent of mods on ships makes sense.
Imagine if everyone’s toons were the exact same stats after being maxed out. The biggest problem is probably that a lot of the community doesn’t like ships and would completely ignore ship mods.
But I love ships and at the end of the day imagine all your toons with identical stars as other players. Lame.
