The raw back-of-the-envelope calculation (based on incomplete info of course so giant grain of salt) would show that if I repeat my season 1 performance in season 2, I would end up going from high Platinum to low Gold (58 to 43). I mean, maybe that sounds better. I hope that psychological sleight of hand works on me. We'll see.
As for the changes in general, the biggest thing that stands out to me is the intent to make each game shorter. This is a very welcome addition; it means if you're being steamrolled, you don't feel steamrolled for as long. I really hope that means people will leave fewer games too, knowing they don't have to stick around for another half-hour, but I'm not that hopeful.
I'll probably continue to stick to quick play a lot when I do play, just because it's more fun and less stressful, but I'd be willing to give season 2 a shot based on these changes. I'll likely bail a lot earlier than in season 1 if things start to go bad, though. Just not worth the pain.
