Should I give up Acheron ?

Hi

So basically my Acheron is E1S1, so I'm missing the precious S2 and I don't own Jiaoqiu.

Basically, I'm a free to play player and was wondering, since it's powercreep time all over HSR, if it's still worth to wait for her and Jiaoqiu rerun to pull both ?

Or should I just keep my jaded for stronger future units and consider that it isn't worth to invest in her anymore ?

Thank you
