problem #1:

unit defending my capital, by some fluke, has negative -2 initiative and thus can attack forever. these 2 archers fended off deadly armies because they could never attack. although it took 5 minutes of clicking.

problem #2:

the sword with the maul ability is too powerful. with dodge, crit, and accuracy i can take down epic armies with a single hero. even early in the game strong creep are easy to kill with my hero by himself. if i get that sword, i win. nothing more to it. even against a full map of ridiculous difficulty enemies, they have no chance against my level 9, 12 damage sword with maul.
