I really wish I could get into moba's, I don't know how you guys do it.. )
I rarely play, it's way too stressful of a game for me haha. But I really enjoy watching it, there's an impressive amount of individual skill and teamwork involved. And I used to be much more into playing competitively, so I feel like I've been there and done that (obviously nowhere near the same level as The International) and it's fun to watch the extremes that things are reaching now.
You can always play normal games because only the ranked games matter anyway. I love to pick pudge or techies in normal games when it is a bad time to play ranked.
It's just a video game, I'm not worried about my rank at all. It just takes such an extreme amount of focus from me that if I'm going to play some online multiplayer I'd rather play something I know the mechanics of so well that I could play in my sleep, like CS or Quake. micro, teammates, enemies, and item progression, for like 50 minutes without a break? A little much when I've just worked an 8-hour day and want to relax lol.
One of these days I'll probably get obsessed though. All of this Tusk play lately has made me envious.
