hmmm...ok i can see what you mean but i really believe that you could never
achieve balance with so much power on everyone......you could at least make the heroes have a lot of hit points...the spells are double and triple stronger compared to other similar games but you have the same amount of life with the
other games...
and you have the BIG diference with having 4 teams(and new heroes) so i don't think you need to differ a LOT in other things(for example if there was also a second DOTA map with four teams i would be plaing on it as much as i play dota..because that's the diference i like..4 teams instead of 2)
anyway it's your map;-) i'm just trying to help if i can :-)
i'm waiting for the new version
