Yeah, they're parasites more than Evilk for Evil's Sake. We might not like tapeworms, for instance, but it's in their best interest for us to stay alive so they can feed.
As for dragons, Alamais was hit by an airplane-mounted laser and lived, but was out of sight for a while so he must have been hurt rather terribly. The scar's a nice reminder of his mortality. Firewings was a tad loco, and lashed out at German airforce assets when they found her. She wound up getting wounded in the fight (Missiles? What are thoOW OW OW!) and went down in radiation land. Rumor has it that she's still alive, but full-blown toxic and WAY crazy. No confirmed sightings, however, just a lot of really impressive rumors. Nightmaster and Lofwyr did the dragon deathdance over Germany, and Lofwyr won. No one's ever said what happened to the body, however.
Ghostwalker fought some conventional assets when dealing with Denver, but they were hampered by the environment and by the groups not trusting one another (Oh Denver, never change!) ... By and large, dragons tend to take the view of "In enough numbers, it could end badly for me. Stay low, get others to do your dirty work for you, and if all else fails, cheat to win."
LESSER dragons have been thumped here and there, or served as parts of a greater force, but are nowhere near as hard to gun down if needed.
