Never seen that, but it's true that ai allied players can exchange units among themself and even with humans. Human, as obviously, has no rights to interfere. So be attentive.I've seen two or more allied CPU Heroes hiring troops in an external creature dwelling belonging to one of them, yes this applies only to CPU players and only when they are allied to one another and the Human player. Otherwise it would not be possible for them to recruite troops from that place by simple flagging the external creature dwelling to their own colour. (can be repeated every week)
That was possible in RoE, patches fixed it for a good reasons.I know for a fact that Human players can't touch anything that belongs to an ally. Perhaps this was left alone as a special CPU players only feature?
.In a related note, the CPU players can use Whirlpools freely without risking losing troops. This is yet another less known fact considering Heroes III
Mm, no, they are loosing units like everyone else. Watch them more carefully Sometimes before the AI enter, if it's having free slot, it just sort out one weakest unit to minimalize the overboard tossing.
The true pain are AI autocalculated battles. Most of them between themselves. These are so fake, at least 50% or outcomes can be sorted directly into the realm of sci-fi.
