Honestly I think it is a great map overall with a ton of possibilities that break up the monotony of some of the other maps. There a lot of options to push into second because there are a lot of openings. There a ton of ways to push into last with some wide open sniper lanes, mid has a ton of possibilities (a highlight being a not quite Process fast roamer rollout but the same type of height and distance to get into the face of the combo walking i anywhere they go and because it is slower the roamer can adjust to the call of the demo), and is pretty evenly beneficial for all classes (except the medic but who cares about them).
It was easily one of the most fun maps I have played this season, the only real complaint I have against the map is that it is a little hard to push out of last sometimes. But ubers are very kitable on last with ways to milk and bait into off-classes to create a better counter uber and get picks to make pushing out easier.
I do also think that Coalplant deserves another chance, the time to cap mid finally making sense again is a huge buff. Plus it's KOTH, EVERYONE LOVES KOTH. If any map needs to be voted out it should be Badlands (i'm tired of this brown stain), Granary (biased mid demo hate), or Metalworks (Etf2l Turbine is clearly the way).
