I find it annoying when I have to build over two metal spots with one extractor. Maybe we could get double resource value from it? Sorry for the short post, couldn't really think of anything else to say really. Meh.
Metal spots shouldn spawn that close to each other in the first place. If there isnt room to make 2 extractors. Sounds like bug to me.
Uber will be revamping the metal spawning algorithm in the future, currently metal spawns in random clusters of 3 and 5 spots.
I´m sure Uber will try to make the metal spot placing better in the future. After that this problem shouldnt exist anymore.
