recalibratiting the waypoints
You have to get the end of the area to access the marker. I have a friend that wouldn’t touch Dry Top for the same reason, yet the only required jumping puzzle-like section is the entrance, unless you meant, you don’t want to jump at all or if lag was your major problem.
The entrance of Dry Top doesn’t really require much jumping, you just need to know how to use the crystals – it’s basically a tutorial. From the first waypoint, you start by taking the yellow sun crystal near the merchant and using the #2 skill to move through the falling sand, pressing #2 again to cancel the movement after you’ve passed through it. You then take the purple lightning crystal and use the #3 skill to jump to the white/blue wind crystal. Use the #3 skill again to jump to the next wind crystal. Use the wind crystal’s #1 skill to jump straight up to the ledge and again up towards where Rime is. From here there are multiple routes you could take. For simplicity, go north west towards where a wind crystal is just before the ramp and fall off. You should see Plume behind you. Follow the path north west, then north east towards a pool of water. Follow the hill up and continue north towards the first waypoint. Use the sun crystal to move across the river of quicksand to reach the first town, just north east of the waypoint.
Now you can do the first part of the living story, which I assume you’ve skipped.
