I like the idea and effort put into it, but I feel like the map has to be more PvP friendly before it should be added.
Also, the narrow stone bridge should maybe be made a bit wider, but I like how the safety railing somewhat prevents people from camping you on the towers.
One last suggestion...
The (what was new) combat system is simply existing long enough now for more and more people to practice and get good at it. Also, it seems that people care way more about PvP now than, say, in 2016. Well it looks like that to me at least.
