I would like to see the Djinns replaced, or perhaps removed, or at least improved. The other units are generally good, and I think the Gargoyles are the best units in the Academy, which might seem strange to some.
I agree... I also like the Gargoyles... if you're playing as Necromancers and only have Plague at the beginning, you can't really counter them... they're cool, and they can fly over walls :) By the way, on classic Gothic cathedrals, these statues are subordinate to the architecture, and their appearance in the game is quite accurate... the Gargoyles that were created for horror stories and myths are something completely different...
