Coming with 20 peasants and simply run away unless AI itself engages? Not even battling? Fleeing with 1st stack that has the chance?
AI will still lose the units so why not enjoy the battle?
The AI still flees a lot in TotE, but I think this is pretty sensible - if it's going to lose all its units without killing much, why should it let you have all that experience? And I think sometimes when it tells you they've fled they may actually have surrendered and kept their troops.
And how can AI know what army I have? I was testing it - going Haven, didn't built any dwelling and watch - it came RIGHT on day 7 so precisely that AI engaged town at day 7.
When I had enough troops - AI didn't come.
They always attack towns on exactly day 7 - which again is a good idea - they often come near my town early when I have far more troops than them and they then run away again. So I think there may be an element of randomness in this, rather than the AI knowing what troops you have. I could be wrong.
Oh, and does AI has some creeping loses? I don't thing so, beating pack of imperial griffins in week 1 with 60 skeletons and 20 zombies when AI engaged my town...or had AI some of 100 skeletons or what? Don't thing so, before AI engaged grffins it had still 'horde' of griffins.
The AI definitely has creeping losses in TotE. In a game I played recently a hero owned by the AI lost nearly half its army on a Dragon Utopia, making him easy to finish off.
And using summon creature without wasting mana? Summnoing 150 peasants with 5 knowledge?
I haven't noticed this in TotE, I'll look out for it. But AI heros often don't have full mana at the start of a battle.
