Overall assessment is warranted, but there are some specific points of interest.
1 particular up top defense point needs work:

Never see the guy up there shoot down at anyone, and I'm not entirely sure it's due to not being close enough to the edge so much as...

...he's facing the wrong way.
Bases are diagonal from each other, not straight across so that's not good.
Bots get hung up a lot on that little step into the side-bases.

(map has 4 towers, 2 teams and 2 neutral)
I was kind of hoping you could setup the UTDMT with monster pathing...

...so they can pace back & forth, although that wouldn't help if they climbed anything as they don't go downhill too well.
