How much more size does a custom created unit/ability/upgrade take up then if you had just edited the base spell to begin with. For example, if you created a new Spell of Storm Bolt rather then simply editing the original spell. Or if you created a new Paladin hero rather then just edit the original.
Basically, does a map take longer to DL/load on bnet if you have all custom heroes/abilities/upgrades?
