First off, glad to know your a mind reader that you say "You know this isn't true."You know this isn't true. Kid Flash is in Teen Titans, Impulse is in Young Justice, Wally West has a mini-series coming up, Jay Garrick has appeared in Doomsday Clock and will be appearing in an upcoming Justice League story. In terms of villains, there are ongoing sub-plots with Godspeed and Hunter Zolomon in Flash, and an evil (Earth-3?) counterpart of Impulse will be in Young Justice.
Complaining about things that aren't true just drowns out and undermines all legitimate complaints and criticisms.
There has not been a Flash family interacting. The one and only time we saw this was with the Grodd story line a year and a half ago. Other wise there are various speedsters floating around in other dimensions and what not. That isn't a Flash family to me.
Also I will comment on what I think is legitimate. Trying to undermine someone else's opinions as not true and just drowning out real complaints is a pretty shitty thing to do.
I'm assuming that the complaints that's you have are of course the legitimate complaints and criticisms. Of course.
