Pirates currently is regular army with brand new ships in perfect condition, regular crew, and fullset weapons, this is not right.
pirates are scum, they shoud pilot junk ships or outdated ships, possibly ships shoud lack shields or use less effective weapons - engine.
also minor portion of damage shoud go permanent and shields shoud also take some *permanent* damage, currently AI may circle around or sit behind shields without any chance to damage it.
For shields - more damage shields adsorbed in combat - more damage it take or minor portion of damage go diretly to hull.
For permanent damage - both hull and weapons health drop permanently and can be restored at stations only, pirate ships spawn already damaged.
