Why the original creator of DotA didn't trademarked the name in the first place if it was so important ? Saying it "belongs to the community" is basically saying it belongs to nobody.
They can still do that. They just can't create a game called DotA. And now no one else but Riot Games can call a game Defense of the Ancients.
So, I was with you on point 1, to elaborate, legally riot games has no grounds. That being said, I know a crap ton of people that will defend Pendragon's cause (not Pendragon himself, just the point he's trying to make). I can see Valve talking this out, outside of court and probably giving special recognition for those that worked hard on this.
That being said, Riot Games does NOT own Defense of the Ancients, nor will they create that game [a game with said name], because so many people made DoTA what it is today.
