There comes a point where if you have enough hospitals that every attack you make actually increases your offence. This point happens when you get more credits than losses during your attack. Obviously this point occurs at a lower % for orcs and elves in general, and especially for war hero's. It would be a function of the amount of elites you have vs specs, base casualty rate (~7% i think) and esp the credit rate (no clue). Some races/pers may never be able to reach this point but I'm fairly certain orcs can, especially war hero's. Has anyone ever set up an excel program or figured out this magic hospital %? BTW, I'm orc/merchant.
