Mid is really in dire need of something changing, it's so open and wide that all you get is 30 seconds of people just eyeing each other, there are very few ways for a roamer to jump without being clearly seen. Most other maps have blind spots/cover to jump from behind, creating a good amount of space for the team as they can jump in without being immediately called. This mid offers none of that.
I talked to you before about this during the phase where it was still being developed actively and being played in double mixes, but I think some of the ideas would try and offer something more on middles and maybe encourage teams to go aggressive more often, in it's current state, any aggression is pretty easily shut down as soldiers are easily taken care of.

Adding a ramp up top will give a soldier another option of jumping without being seen straight away, it also provides another position for someone to jump to when going aggressive that isn't just on the house.
I'd also remove the path in the bottom left as anything that comes out of there is pretty much dead, it's easy to see.
Not only that but it encourages people to go behind, which one a mid fight you don't want as it just makes it worse, badlands does a good job of this because you can get behind through choke but it's high risk, this however isn't that high of a risk. Going behind through the cave is a lot more high risk as it's easily seen, it also doesn't have much HP so if a scout gets hit going behind he's only got a small kit (like granary) to get back in the fight with.

The next part is to try and include some borders underneath the new ramp to again try and get some fucking surprise on this map, I'd also suggest completely fencing off the parts on the side because they really don't offer anything and should just be there to provide a bit of cover. At the moment anyone that goes there just gets shat on by a demo.
My final issue is with the shitty ramps near the point, please make the entire section a ramp, like how process has on last, so you don't get caught as soon as you go on to the point. It's really shit and I feel it doesn't encourage teams to move over as you can easily drop down to the point but you can't get back up.
The only other point that would need addressing is to provide some further cover on the middle for soldiers so they can jump, my ideas are only slight ones that might help. Every other map provides some sort of clear cover for people to aggressive without being seen right away, for me this is the major issue of this middle as I said.
