There is a rumour going around that Rammus and Teemo were both based on fan-submitted concepts for Dota heroes back during Guinsoo's time. At most they were stolen from their authors - not Dota. However, I would assume that those concept were given to Guinsoo to use - he just used them in his sequel (League) rather than Allstars. I cannot state if this rumour is true or not, nor do I think it would be possible to confirm it unless the Allstar forums are still active - I could easily believe that it's a vicious lie invented by Dota 2 players (since they seem to really dislike League of Legends for some reason).
