Putting world bosses in instance is bad. It’s not even a world boss anymore.
Couldn’t they just spawn more often? Make them give personal loot (must be rare tho) with weekly lockout (or less w.e I don’t care) ?
First faction to tag and kill get the loot
That would fix the issue with guild monopoly. Random ppl would group up together to kill it, also keeping the pvp scene alive.
Other than that idk how they could fix it.
I’d rather have the era world boss than what they have planned
