Huh? u mean that players can buy upgrades? I kinda like that, tho I am not totally sure. Another thing: You could buy ur own units that go to YOU so you can control. OR they could go to Night Elf or who ever u are. =) Another thing: You could like, buy a unit (or hero) with no spells or anything... and 1 damage, 0 armor, 200 health (if they are heros they would have 1 of each stat) You could buy items for these and they could use them. =)
