Lies DC. As a former cheater, I know you can actually make up to like 10MB, then use Vexorian Optimizer to get it down a notch or two ;). + Any map over 8MB can be hosted in SP, but not on battle.net ;). Also, the 81 heroes can easily be set down to like 50. You'll still have LOADS to choose from. Maybe just 60 (Cutting 1/4th off). Which saves you 21*300 = 6300KB. And 9300KB if you cut it to 50 heroes. Also, the hero skin is not needed to change after each + :D.Ever played Angel Arena Allstars? THere are some weapons that actually gives the wielder a sword or a shield. There are even some with glowing effects
