Game Mechanics: MELEE PROBLEMS (Mob hit rate, # max hits, etc etc)

[guineapig]

Soft Caps
Cloth..........= ~75 worn AC (yes its really that low)
Leather......= ~100 worn AC
Monk..........= ~120 worn AC (if they are under 15 stone wieght)
Chain.........= ~200 worn AC
Plate .........= ~300 worn AC

Has anyone checked to see if maybe the soft caps are screwed up in the code?
That would explain the diminishing returns of AC on tanks being off.
