I wish M2TW would work on my 'pooter.Yeah I've been wondering about that too in RTW, in M2 I've set them on fire with archers though.

Don't combine two plurals. It's either Ballistae or Ballistas.Ballistaes
take too lnog to load and fire too be effective in RTW it seems to me, I never use them or catapults. I'd rather have another unit of calv or infantry.
You should try out Scorpions: they have longer range, are more accurate, and do more damage, with the drawback of being ineffective against buildings. I tend to not use siege engines at all, simply because they slow my armies down, and the foundation of my offensives is the Blitz; once their standing army breaks, the AI has a very hard time forming a new defensive stratigem, much less new armies.
