Lone scouts are one of the few realistic roles left for small ships.
In SE4 you never need to transport a few people or small amounts of cargo.
There are no limited-conflicts or wild space where you'll have to defend with small weapons, you have either safe systems or heavily defended enemy territory.
Small lone combat ships are pointless because they are only likely to face massive enemy fleets.
IMHO Proportions overcompensates this lack of roles for small ships forcing the player to use small ships to make his as massive as possible combat fleets.

I like that there is more contrast between large and small ships.

IMHO torps need a better damage ratio in adition to that to hit bonus. Either decrease their tonnage or increase their damage.
