I was lucky enough not to have any black map problems.
It's not that I mind resummoning allies,like you said there's plenty of restoration potions,but I really enjoyed reviving enemies after a big fight
and having them follow me around.It was fun to see dragon riders deal with the
imps.However there's no point in reviving them if you can't order them to come
along.I must say that although the game itself is a real joy,the patches are less satisfying,a lot of nasty bugs still remain:
-game freezing if you repair an equipped item (to avoid:unequip)
-game freezing if you click on a poison potion (to avoid:drag into inventory)
-broken skills (makes using anything but a sword rather pointless)
-freeze or crash when using revive + aura of command (makes playing this way impossible)
I love this game so much i like to replay it,but those last two really limit
the game's replay value.
