Sync bugs aren't really the problem. It's no longer very common. Right now the biggest issues, other than the lack of people who play it online, is getting the Lobby channel fixed, minidumps, ICO lag, and games that drop from ICO.
Lol,you forgot the balance and human factor.Most people are asshole's and scare newbies away with OP strategies or asshole attitude.Like always going marza and spamming LRM.....repulse is a problem too...fighters are almost useless.....marza,again, is operpowered crap.....illuminators are OP in fleet battles......vasari phase missiles are 100% death to any advent cap......TEC protocol override is OP......and a lot more.
oh,and capital ships need a boost, in hp at least....doesnt matter how exactly - they are too fragile.
