The boss encounter rate has dropped significantly after the first week of the event, to a degree where players who didn't complete the seasonal quests during that time are at a significant disadvantage to those who did.
We're over halfway through the Murkwood event with no word on the encounter rates, leaving players unsure about whether or not it's intentional.
Some players have been holding off grinding for the seasonal quests due to this, as it's noticeably slower to get through the seasonal tasks with these decreased rates, hoping that the rates will be brought back, or at least get confirmation that it's an intentional change.
I think it's only fair to give us an event extension due to this
