I love A/D, but I didn't really enjoy this map. Even accounting for lack of memorizing the map layout, people are calling this a maze due to the abundance of 90 degree turns, height changes, and many spirals. It felt grueling with tunnels, unintuitive chokepoints/flow, 20 minute Dustbowl timers.
Just because Dustbowl does it, doesn't mean you should do it too, is my opinion. Erebus feels like it copies antiquated map design and I believe suffers for it. When people were hoping to complete their contracts before the map ended so they could avoid the map, that looks like a bad sign. And truly, I don't want to defend the last point on the 3rd stage for 20 minutes, nor do I enjoy backcapping *because* I don't want to play that long.
3 stage maps take a lot of work, and I am still glad to see something new this Halloween. Truly most of my negativity bias comes from the same issues of Dustbowl or Egypt - you have to be in the mood to play those kinds of maps. If I treat this as Halloween Dustbowl, I like it. I just don't see myself coming back to this map often because of that long round time. I'd rather spend that time on other enjoyable maps.
