Thats exactly what i do, using drone hosts(full bombers if no counter) or illus as my dps in the fleet. But in early game i just cant get the titan low fast enough with such small fleet. I get him low but it takes some time and since titan is low its already taken out like 15 frigates and then just retreats to regen. Would take me few jumps to kill it but by then he is already regenning from repair bays and i still losing my ships while i havent killed anything his. Even worse is when i try to attack the planet where few repair bays are together, then he just moves in and out all the time...taking out my frigates and gaining xp for his titan.
Same goes for mass cap ships, when someone has 4 kortuls and 1 or 2 support caps. Ofc i try to take out support ones first, but they still get away with 20% hp. If im lucky i manage to get something down and thats only if he is not paying attention. Everything has over 3000 hp and not a single frigate to kill, if cap is starting to get low, he will just retreat it. By fleet dps and damage done i for sure am over his fleet but i cant kill anything. As AR i dont have any serious regen abilitys to overheal caps dmg with only 1 mothership(prolly not even with 2), tried with culture spam and 150% shield regen, not sure how does this tech work exactly tho, if im on enemy planet wheres my culture is present and his isnt, will my shield regen work? Even if it does its still not enough to heal over caps dmg. Only thing that seems to work is kite with drone hosts around the well but thats just temporary solution.
When titan gets in im deadmeat, i was against 2 kols, 1 dread, 1 dunov and ragnarov(thats only 350 fleet supply), i had 15 drone hosts(300 fleet supply), mothership, 2 revas, halycon(200) and few illus with guardians, around 650 fleet total. My caps were getting nuked so badly, in 1 min i had already retreated all my caps(lost mothership) while my bombers were chasing retreating dunov with 30% hp( and it got away).
