The current meta is TIE Advanced (easy target locking as well as dispelling), FOTF (inarguably the best damage dealer of all ships, plus hitting target locked enemies makes him faster), Biggs (best tank, impossible to replace as main tank) TIE Fighter (dodgy damage dealer that speeds up fleet but is weak against Vader) and Reaper (specifically due to its tmr for capital ships) when it comes to reinforcements there are some that guaranteed fit the bill such as Scimitar, i have my doubts about Slave 1 it does have good HP but it lacks defenses, it soaks up damage like a sponge, TIE Silencer is a very good damage dealer that can stun and it can change the tide but it has one glaring weakness, the Advantage needed for his special, i would suggest getting Gauntlet thanks to its Empire synergy, with the Solo movie coming out we just might see a new imperial fighter coming along, there are also rumors about a potential TIE Defender which will guaranteed be a tank, the best ships are Empire for a reason so getting Gauntlet will just make it stronger, every faction has that one synergy ship and for the Empire its Gauntlet so its a good idea to consider it, as for other ships its a bit difficult, Falcon is a glass cannon, hits like a truck but dies instantly if targeted, Wedge wouldnt be that great, some say Shuttle is good but im not entirely sure on that, for some reason i cant find anything on the FOSF Fighter, it has good abilities but i have no idea how it performs in combat.
