Siege mechanics in manual wrong?

Mindless units crack walls really fast. Lankan soulless are the cheapest wall-breakers. I think, they don't really have a penalty for sieging, because Breaking is always easier than building

I think you are wrong. If the soulless has 20 strength its value for tearing down a castle is:
20*20=400
400/100=4 (non mindless value)
4*0.1 (for being mindless 90% off) = 0,4

So 4 for a none mindless and 0.4 for a mindless, both with the strength of 20. I would say mindless pretty much suck at sieges.
