Running away from a Lilith is nothing to be ashamed off. That thing is the most overpowered and imbalanced ship out there.
Well, it's not.
And here's why:
The Aeolus, a pretty light cruiser is armed with:
2 Terran Huge Turrets (2100 m range, 3.0 s between shots, 175 mps blob speed, hull damage per second - 41.7 HP/s, total 83.4 HP/s),
6x Standard Flak (1400 m, 0.15 s, 700 mps, 200 HP/s, total 1200 HP/s- although it'll max out only against big ships due to spread),
2 AAAf's (1500 m, 5.5 s, 24 HP/s, total 48 HP/s)
2 SGreens (4000 m, 45 s, 61 HP/s, total 122 HP/s).
Total damage per second is 1453.4 HP/s, deadly to both capships and strike craft, and hurts from any angle.
It has 38 000 HP, max speed is 30 m/s.
The Lilith, heaviest cruiser in the game:
Shivan Turret Laser x 5 (1250 m, 1.2 s, 250 mps, 50 HP/s, total 250 HP/s),
Shivan Cluster x 2 (450 m, 20 s, 90 mps, 3 HP/s missile+ 12 HP/s for the 8 bomblets each missile launches, total 30 HP/s)
Anti-Fighter Beam x 1 (1500 m, 5 s, 20 HP/s, total 40 HP/s),
Large Red Beam x 1 (4000 m, 10 s, 1359 HP/s),
Total firepower: 1679 HP/s (about an Aeolus plus 2 Kaysers), concentrated in a single, easily disarmable turret with a limited field of fire, defense against strike craft is a joke.
It has 75 000 HP and a top speed of 20 m/s
