Honestly, there are heroes who just take up space. If you pay to play, like me, you can wind up with some dead-weight.
Right now my backlog includes 3x Wu, 2x Li & 2x Hu. I have no problem with one or even 2 Wu to go along with the first at 3^60; however, I see no reason for keeping any of the HuTao if I keep all my Li Xiu.
Not looking for advice on these so much as how do you all make these decisions.
I am not an event player, but more focussed on titans, raiding and AW.
