Traited Wings of Resolve bug
This might be a similar issue to the thief’s staff 5 skill, which also cannot seem to reach it’s full range and lands before the area you’ve targeted.
I think some have suggested a bug where the skill counts the actual aoe circle’s radius as part of the maximum range, so the apparent cast distance shown is inaccurate or bugged out somehow (basically it would be the distance stated in the tooltip, minus the radius of the aoe effect, if I’m making sense). Perhaps Wings of Resolve suffers from a similar issue.
