This morning I read about "Dota Client", which I haven't heard about or used before so I figured I'd download it - only problem was I couldn't find a working download link, the "official" had a wait time of nearly and hour, and all the forums I found with it required me to register but then kicked me out every time I tried to download the file.

Eventually I managed to get it, so here it is... a download link for Dota Client 1.8 (dcsetup-1-8.exe).
