I try to take the roles from Discovery into consideration. Light Battleships like the Mako I'd definitely put in the high tech range, trying to stay at a distance while Heavy Battleships like the Valor and the Tokugawa are tanky low tech ships.
The Valor, for example, is very slow but has the FWG and an Ammo Feeder, meaning it's ideal for short and mid range, and the Tokugawa, while being slow, can jump into battles with the flux-heavy phase teleport system but not out. Ideally all capital ships should feel job-specific and be a bit different from the class equivalents of the other factions. Sadly, this will be a bit difficult with fighters/bombers, but I think the gunboats will at least feel unique.
