The fires of hell have opened up (unless you live in Minnesota, where you just got slammed with another Blizzard) and Diablo 3 is offering another weekend of increased XP gain for all characters.
Personally I'm having a blast in Diablo right now. Reaper of Souls' adventure mode is holding my attnetion like nothing else has in a very long time. Plowing through packs of enemies on Torment 1 or 2 and getting gear that actually matters is an amazing experience. Plus, the legendary gear has interesting bonuses on it that make the gameplay that much more fun.
If you haven't picked RoS up yet, do so now. You won't regret it.
