[Spoiler]

How can "ninja expand" even be a thing on a map like this. I mean if you are not automatically attempting to capture both corners from the very start then you are clearly doing something wrong :P

It's not like the map is particularly big.

The strengh of the sneak expansion on this map lies on the 2 major expansions being out of the way of the normal engagements + being far enough from normal radar placement thus allowing the player to claim it very early in the game without the knowledge of their opponent. Once their opponent relalizes what is happening it may be too late to react since defenses has been placed already.
