Although that doesn’t really address your issue since a single Jester Champ can instantly kill every member of the Team in a single Bomb barrage (along with any players trying to rez them)
The only way to beat this right now is to NOT have more than 5 people anywhere near Meddler’s (which is almost impossible b/c lots of people just AFK there out of sheer habit)
Any event with a mob that can instantly kill the team being escorted and dependent upon that team staying alive is bad design. I really hate these types of events.
I don’t mind the escort ones where the escort dies, the event can continue since I can res them. The ones were it is fail on death I detest.
