for me personally it doesn't really feel like it even on lvl 70 lol. maybe it's because it usually takes me a lot of time to do the new endgame modes like su or du but i don't really want to do the same thing again and again, that's boring so yeah rip the jades for now.
also to me the amount of new five stars you should probably pull to clear the endgame content + powercreep kinda negates the generosity
