your questions regarding the game rules (improving the interpretation).

It's a bit strange how you're judging, gentlemen. Whether something is a "block" or not often depends on the army you're facing. For Shakti, with 50 troglodytes, anything is a block, but with 150+, nothing is a block. So, the formulation "with losses exceeding half the army" is perfectly adequate and has been around for a long time.
