Whats DOTA?

Can someone like, mail me their WCIII disks? I have CD keys... My disks just got so scratched they no longer install D: aha. If I could I would play with ya'll.
(which is what I'm currently doing now).No need to download a torrent bud, just go on the Blizzard store site and you can download an electronic copy, you just need to register the CD-keys first.
Even if you have the CDs you should just use this method because it lets you play without a disk(which is what I'm currently doing now).
