Was wondering if anyone had suggestions on what might train Athletics after 420 around Crossing....currently hunting maulers and warklins so any where in that area would be a bonus. The walls are starting to not teach anymore, at least with practice.

I do a loop that swims the river, climbs the tree, and also hits up all the walls. The walls add about 3 mindstates hitting all of them for but the time involved (no rt) its not a bad addition to the loop for me for now.

Pretty sure you can run through the undergondola area at those ranks can't you? Walk (and eventually swim) across the Segoltha and its a quick run.
I think I started climbing there at less ranks than that.

Run up and down all the climbs, pick a quiet spot to collect rocks or whatever for a minute, and then repeat.
I used to stop by there a few times a day to quickly lock it while training other stuff between climbs.
