I'm just blowing off steam, as my vamps seem to have the same problem all my teams have, namely, can't break AV, and when they do, only get stuns.
Had a practice match (against myself) vs. a all halfling team (yes, I know, no-one plays a 16 man 'fling team, but it makes me feel better sometimes), and with 2 st5 and 3 st4 players I managed a pathetic 3 cas, 4 or 5 KO's (all game) and shed loads of stuns
Someday, when I've some time, I'll go though my old game logs and actually work out my "average" AV and Inj rolls
