MF Gear Swapping debate

How often does it appear though? Cause that was the first time I ever saw it. I was on my way to Leo's Manor when I saw it and was like, "wtf is this place?". I was pleasantly surprised, needless to say.

I've seen it more often than not in that area. It's like any other cave or feature. I think they have X slots to fill of 'features' when it generates the level, and the caves and events each fill one. You just haven't gotten that one drawn for you before.

The watchtower level 2 always seems to have a lot of packs in it. It's rather dangerous since they can be quite close - you are likely to pull 2 at a time if you are not careful.
