This slow tactical battle for now is game breaking for me. And this is why:
One AI got infinite debt bug, he is at -200k or so now. Because of that he can pump out endless armies, and that is reason i cannot lose even one unit or its game over.
Only way to do it is to use ranged units + freeze spell. Fights are usually pack of trolls vs 4 mounted archer squads + 4 sovereigns . Problem is that recent troll groups have 1000hp, it takes about 45min to kill such pack with archers, one archer attack takes 4-12hp, animation lasts about 10sec.
This forced me to use burned ground (capture towns and raze them) tactics against AI which i do not like because no AI yet can defend against it in TBS games i played so far. This feels like stealing candy from kid and immediately throwing into trash. Also while i am really excited about winning this game it gets sometimes boring during 1 hour tactical battle with pack of stupid trolls.
