Wholeheartedly agree, there is absolutely no need for a new map and investing resources into such would be a waste.
I was already skeptic with Siptah especially since there is nothing connecting it to and from the Exiled Lands and as such seems another wasted opportunity.
I know enlarging the EL play-map so to speak is a pipe dream and probably unrealistic or otherwise not feasible, but there is still enough room to work with above and let’s not forget below (caves, caverns, underground passages, underworld/hollow world).
Aside from bug fixes and QoL that’s where I would wish they also focus on and I would easily shell out for instead of another armor or pet skin from the Bazaar.
