Overall I think the layout is matchmaking worthy. But like you stated, tweaking and testing spawn locations, Color, and accents will set this apart from any old forge map.
I have had the privilege to play with STRAY morais, and help him with the color scheme of the map. Overall i believe it is a great map, however my review may be biased.
From what i have seen, the map has been overhauled a great deal since the first iteration. From downsizing the map, to the war with framerate. A lot has changed. I believe the map is in a more stable state, but there is a great deal more that can be done to perfect the experience. I am not sure how well it plays with slayer, but i feel strongholds becomes very competitive.
Why 5 stars then? Biased.
