The main problem with a red rush is that for every 1 real red rush, there are 10 "red rushes" where a hero with growth stumbles upon an opponent's scout hero or an empty castle. It is precisely for this reason that the idea of allowing red rush is being pushed forward, and not at all out of a desire to help the red player. That is, to make the flow of the game more natural and less burdened by rules.
