Classs changes:

1.
heavyfighter = {
ship_m = "M6",
ship_s = "M3+",
},

to

heavyfighter = {
ship_m = "M3+",
ship_s = "M3+",
},

Reason: The only M-class heavy fighters, i've seen are the Khaak ships. Both are not M6 corvettes. One is a old M4, the other is the old M3. Their firepower is same as fighter/ heavy fighter of S-class.



2. The support ships, are i think:

resupplier = {
ship_xl = "TL",
},

Personally i changed it to;

resupplier = {
ship_xl = "TM+",
},

They are not common TL. Their main purpose is support ship role for fighting ships. They are lightweight carriers with this resupply speciality. So i went from the lightweight TM fighter support to TM+. The "M" is military, what would fit to the resupply ships. + because, there are huge differences to the old TM class.

3. I also changed couriers:

trade = {
ship_s = "TS",
ship_xs = "TS",

trade = {
ship_s = "TP",
ship_xs = "TP",

Much better speed as a common TS, also much smaller storage bay. Like the old TPs.
