Capturing, rendering, and uploading this video is faster then the download for this game, the validation for this game, and the repair for this game.
From what I've seen the game looks like a lot of fun, I don't want to judge my experience on 4 hours wasted installing the game and then repairing it because my mouse won't show up when I first try and play. However to know about this problem (in the FAQ section of Hi-Rez's website) and force your players to go through this slow process to fix the problem is a pain in the ass.
Don't even get me started on the client.
