Oregon currently is a MUCH more stale, boring, and repetitive map that shows huge flaws in its layout composition.
It is also healthier in the long run and more interesting to see maps that force different approaches to strats.
The players are the ones who voted it out. If a team thinks they can win on a map that is all that really matters. It doesn't really speak to the strengths of the map. Very few top teams avoid Coastline for a reason.
