Trying a JYD run, and very much enjoying it. Overall feels rather good and I absolutely love the ship names. The Blaze weapon line feels too short range, but that's just because energy weapons feel too short range in general
That said on the 'actually criticisms' part, the Irksome is incorrectly treated as a Civilian Ship by the game, which while funny because it makes early pirate fleets suicide on you, is very odd since it's as tanky as a destroyer and with Drill LRM/Brawler missiles as standard, which combine an Asteroid Burster Cannon for anti-shield and it's drones means it does really well as a massed slow frigate, and if you have Carters, you start with a free shield blueprint rather than neading to buy one. [Edit: The same applies to other militarized vessels such as the JYD's Valkirie, who while not great in combat is clearly actually built for it and isn't a civilian ship until you take it into combat and it runs away from Kites like a ***.]
Additionally the Particle Emitter weapon line seems to have too much EMP. For example compare the Phase Emitter and Ion Beam. The Ion beam puts in good work in Vanilla, the Phase Emmiter sacrifices 100su and 3OP for 6x the damage and 13.75x as much emp damage AND better flux stats meaning it goes from 'Interesting Utility' to 'Dedicated Anti-Armor'..
A PD laser is 400 range, 4OP, for 75 damage and 40 Flux, a Particle Emitter gets an extra 100 range, double damage and as much emp as a Ion beam for 70 flux. Honestly as a weapon it's so amazing that on some ships I want throw on PD Prep and use it as a primary. [It's only a want since I can't find enough particle emitters for it.] [Edit: Also, I thought it was suppost to negate engines by being an EMP weapon. It might be worth clarrifying that it has the same anti-movement effectthe Graviton Lance is supposed to have but dialed up. Really noticable at 2-3 on target.]
As for the Drone Fighters all the ships get, they're almost all equipped with Drone Guns being Kinetic Hard Flux instead of Energy Beams. This is astoundingly better than Mining Drones, to the point it's barely worth bringing Kinetics on certain ships since fighters do it all for you.
Lastly before I forget again, the Armored MRM's description is broken, a bunch of the text is replaced with a % at 2 places it seems.
