Some of the in-dungeon events are literally impossible to complete with a mastery tick. Mostly this seems to be the ones where there are a number (2-3) of NPCs which you must protect to complete the event.
I thought I would make a post about this now, rather than earlier when I encountered this issue, believing it might just be a skill issue on my part.
However now as I’m further into the late game, I’m convinced the scaling is simply messed up on these NPCs.
The example I will use is in Blind Burrows. The NPC’s literally die to one-two hits from the smallest spiders that spawn from the first waves and are dead immediately.
I base my conclusion that this is not a skill issue on the fact that I am running a Pulverize druid, and I’ve done these events with a full bar of spirit, and Harmony/Artillery buffs, literally able to spam + 1shot every mob that spawns during the event, and yet somehow the NPCs are just immediately dead within the first 2-3 seconds, every time.
These NPC healthbars need to be buffed, or they need immunity from ground aoe, or something like this to fix the issue.
