WC1: Love Dralthi -- The original flying bullseye! Hated Gratha, especially when I had to fight them in a Scimitar
Oddly enough, they weren't nearly as tough for me when flying a Hornet though.
WC2: Drakhri -- It's just another bullseye. Hated the Grakath, I think they had 2 turrets back there.
WC3: Dralthi -- Notice a pattern yet? The flying bullseye returns. Hated Vaktoth, but one DF in the face sure did a number on them.
WC4: Hellcats -- I didn't much like flying them, but they sure easy to blow up. Hated Dragons #@#% cloaking device.
WCP: Lampreys -- Crummy shields, pathetic weapons (Did that weapon actually do damage???) the perfect target. Hated Devil Rays (Spits on one, misses, hits a Dralthi, the Dralthi explodes.)
WCSO: Haven't gotten far enough to say yet.
