To 50, or not to 50?
enthusiastic noob
I don’t think that table’s telling the whole story. As I understand it, the karma reward is for playing a level below your personal reward level (capped at a 10 level difference). That table is showing the maximum this can give at each level, with the sweet spot being a level 50 running a level 40 fractal.
It also depends on what you’re running fractals for. If it’s for karma, then yes, level 40 is your best bet if you’ve reached level 50. If it’s for a chance at the skins, ascended chests, or the tonic, then you want to run as high a reward level as possible.
