The new Persian war elephants look quite different in the E3 trailer. They now have heavily armoured heads for instance and look totally badass, IMO. If there’s one thing I’d like to see changed, it would be having a mahout (rider) put on the Persian elephants. This would make logical sense whenever a Persian elephant unit is converted - since monks converting riderless elephants makes no sense, whatsoever.
That is unless medieval ‘holy men’ had a secret ability that allowed them to converse with animals - in which case they should have no trouble converting zebras, lions, wolves, crocodiles, sheep, and GAIA elephants too - unless there’s something about war elephants that makes them special.
I wonder if the developers read these forums occasionally, and if they might be able to consider a request to have the Persian elephants changed so that they are ridden by people in the definitive edition.
