Until now, it was not really hard to get +10 for weekly chest thru pugs.
But, this week I had so many failed attempts to upgrade a key. Highest issue comes at +12, I had 5-6 attempts to upgrade key at that stage, but no luck, its either dos or healing or tank issue.
Also, was MoS buffed? Quite a lot of problems there, wiping on all bosses.
Anyone has similar experience?
