Also I agree with you about the damage increase and attack speed increase. RoC DotA was great because you could not kill a hero that was supposed to be a tank in like five hits. Also the lumber thing, where you can build towers in the place of enemy towers is just gravy, a very strategic addition to an AoS type game IMO. Also I do not think that you should be able to upgrade creep damage/armor because it would allow the teams to exploit creep skills to overcome the enemy creeps.
