Reduce Spell Creation Time
This has been a pet peeve of mine for awhile now, but it should only be a minor balancing measure.
Reduce the time it takes to create spells. It doesn't need to be an earth shattering reduction, but it's annoying when trying to attack during wars and waiting 3 hours for my spells to finish.
I get that some units have long creation times too, but there are also multiple barracks' that they can be trained in.
....another spell factory could be added too, just for making spells, not increasing the max amount.
