After playing some lately I realized that part of the feeling of classic that I think is missing is that incoming waves don't immediately come through one of your world's wormholes to attack you. Instead they come through a warp gate and then are added to the threat fleet.
I am thinking that they should attack immediately and have similar behavior to how waves carried on in classic afterwards(e.g. retreat, push the attack). Does anyone else think this would be preferable behavior or do you think the current mechanic is good?
