Not only did this make me feel like going back to dota after dumping my IP for nothing, but completely ruined my interest in the rune system.
It might not be totally random. Thought it roughly is. Try looking at the primary/secondary colors and checking your "mix" when you are combining. As the first post said, early on it's completely random while later you can get certain packs of runes.
I think the mixture of the primary/secondary can determine your color and it's primary and secondary that comes out.
Just an early guess though. Haven't tried it out very much.
And I also didn't read all the pages of the thread, maybe someone has mentioned this already.
