probably not everybodies cup of tea but I beat my former record on furthest jump after discovering a (easy) way up a little higher ramp then the Vista explorer from vale, using the momentum of it's edge, shadow walk, ranger sprint boost and a whole bunch of abundant steps I managed to jump straight from Vista (south west) all the way up the stairs to coalescence chamber! (all the way east on map). I combined some pictures of the minimap to show the track and also as somewhat of an evidence.
Ps. monk/ranger is still the fastest class with a maintainable speed around 75KmH and top speed of 96KmH compared to a base speed of 25KmH. druids seem to get closest now at 59KmH. Didn't get to measure druid + barbarian lv 1 yet however, they would get really close to monks. Anyway below the picture of the jump.
Approximately traveled 1560 meters through air.
