Adding to it the Blizzard's takedown of this legacy server, why the fuck people think they can just rip off their work? They created it, they invested the money and time to create entire client side + all art assets ( and server is maybe 10% of the whole ).
You dont have fuckin right to steal someone's work. You just dont. And im not speakin defending any company, but i would be pissed on the same level if someone did it to me. It does not matter if its a legacy version, if its 10 years old. If you feel so strong, create your own game, do what LoL did to DotA - profit.
