The van removal was a good move - it was way too easy to camp the courtyard area for defense even before losing the forward spawn as well as the issues with bypassing the wall. In the original W:ET Oasis which this map is based on there was the covert door which allowed for some backplanting + you could trickjump over the wall via the forward spawn side though I don’t think this was intentional.
I think its fine to allow balcony access to attack via trickjump as long as you can’t get behind the wall and into the 2nd objective. Maybe blowing the door opens up other routes to the 2nd objective area:
Green = trickjump allowed area
Red = out of bounds until wall blown
Yellow = containers allowing trickjump access
Black = wall
Blue = plant area

Would need to ensure that the green area doesn’t help spawncamp defense (prior to forward spawn). Maybe trickjump is only allowed when forward spawn capped but would have to make it obvious somehow. Defense can currently hole up in the room behind the balcony with healing stations and medics who are unhittable.
