Shady oaks was always my favorite map. It was extremely underrated for how intricately-designed it was. Another fun one would be Woodlands, due to its varied gank points. Sadly, these maps aren't the most popular, so they probably won't get selected, but I still have hope for a release somewhere in the future! Bring back Shady Oaks! There was also one with a campsite, looked like this.
I have fond memories of this map, but unfortunately it's not listed.
Club Titiboo was one heck of a map, and I can't wait for it's remastered/refurbished release!
