A not angry question for riot about dynamic queue

Okay, so you want dynamic queue to work better than solo queue eventually. That's fine. But why can't you put solo queue back and have playtesters/pbe work out all the problems and imperfections that dq currently has. If I'm not mistaken, that IS the point of playtesters and it's the reason why the pbe server even exists.

I think the best course of action would be to put solo queue back while you fix and perfect dq, I see very little reason why this can't happen other than not wanting to conform to the communities complaints (understandably)
