Yeah I think that's what people have been wondering in the past. I think that sounds too ridiculous though. So it basically means just 25% reduced success chance.

Another point in the dragon page to look at is the third point under Dragon Behaviour. It's outdated. I know I can change this haha, but if someone else can do it, that's great too. I don't have a wiki account yet =P. The point reads:

Every soldier sent will destroy 1 point of strength. Every Specialist will destroy 5 points.

The point immediately above that is correct; no points need to be added saying how dragons are now slain.
