I don't think I would have this pet if it weren't possible to AFK on the training missions without getting punted. I played to level 8 or so legitimately, but it's just so repetitive and boring, I doubt I would have plugged away for the number of additional hours needed to acquire Graves. Once I discovered that you can just start a match against computer AI, tab out for 30-40 minutes then return to collect your xp, it was on.
I know people criticise those who do this, and I don't particularly like it either, but I honestly think it's Blizzard's fault for making the time investment so big. I'd be fine with spending a few hours on something i perhaps don't enjoy that much, but this was 30+ hours of play to get the pet legitimately, and I value my spare time too much to spend that long doing something un-fun.
Collect Graves...how???

I'm on holiday now for two weeks, so definitely safe to say I won't even pretend to do this soon xD
