Some things I love doing in the right situations...
1) Spam LFs and Corvettes late game...sometimes you'll see VL players spam carriers and overseers without a whole lot of other ships...these two ships are great counters, move fast, don't require labs (in case you lose them to VL), and don't have the limitations that carriers do (long build times + squadron build times, AM being lost after each jump, slow, firepower vulnerable to JW)...its definitely a niche strategy, but especially if you are supporting an ally who has titan and bombers, this can be a great fleet to deal with late game VL...nice perk too is that by being fast, this fleet combo has better chance of catching VL or running away...
2) Get 2nd akkan after Titan...if you manage to get both to lvl 6, you have 2 instances of armistice, which is awesome...happen to get one or both of them to lvl 8, and you have armistic almost indefinitely...because armistice has a range limitation, if you stay away from the enemy fleet then they don't get the invulnerability...this allows you to keep your ships immune to bomber spam, but still use your bombers and/or fighters with impunity...having the 2nd instance of armistice really is crucial to pulling this off though if you are facing massive bomber spam...
3) Resupply/Docking Booms...it's not perfect, but it can be a godsend in protecting your carriers and HCs from AoEs like those of the Rebel titans...again, only useful if you know an attack is imminent from a Rebel player who is relying on their Titan AoEs instead of bombers for damage...
