Level 93 and still weak

I have this problem when it comes to fighting other vamps, sometimes I think I'm stronger than my target vampire because my skill ranking is higher but when I attacked I get this nasty message "Unbelievable! You LOST the fight along with 100,000, taking 22 damage and dealing 22 damage to your enemy. Your skill ranking decreased by 0" since I don't exactly know how that happen I come up with a conclusion that always fight a vampire that has at least less 200 than your skill ranking to be safe.

Right now my current skill ranking is 4,393 and my focus is to get more minions until I can support 501 Superior Horrific Transformation, 501 Superior Impervious and 501 Superior Flight.
