You won't be singing the same tune, friends, when the formulation you proposed decides the outcome of the game against you (Mulligan will break through difficult blocks, because he can also have a tactic, and Isra will crit and kill 300 skeletons in a day). Now imagine a situation where one person has all 3 heroes captured in prisons for several turns, while the other has twice as much garbage :)
The rules should remain as they are, only their wording should be adjusted to avoid ambiguous interpretations!
