Key#3 - after 27 attempts. Snoofo you've been in some, thanks mate :)
It took all up about 9 hours to do it. While was hunting for 3rd key, found 3 legs and 2 set items, average quality. Gained 3 paragons and about 5m gold! To me this is what Bliz wanted to do us. Yes, I'm happy, this is a game.
Now, if at MP1 I have 10% chance to get parts for a ring, should I better to hire professional killers and jump on higher MP, or go solo and hope for luck? Or may be wait until I will be OK to do MP7+ solo...
What's your experience?
