Classifications are always going to differ for each server, for instance craftau has a bunch of 350m 60,000 mass "destroyers". But that last list would count them as dreadnoughts.
With the fleets and upgraded ai, when that finally comes out! Fighters/bombers will play a greater role.
The thrust mechanic has changed the game enough for them to have a use but the ai must be smart enough to stay to either the sides or back of their target to stay alive. Staying out of the main frontal fire arc, the fighters can deal their damage where only turrets and point defense can see them.
Also having multiple ships in engagements means the placement of turrets and their firing arcs may have to be a little bit more thought out, this will also hopefully get people to pilot smaller ships in favor of more ships
