Speed isn't everything. If damage was tuned down a little we'd have a completely different game where reactive play is possible. QGJ definitely needs a nerf currently if you're arguing for nerfs on the characters you listed above.
Also, you're referencing speculative numbers about level 70 stats that are unconfirmed, and calling for a nerf in part based on this.
A tank that does practically Barriss level damage isn't the problem at all, it's the possible damage from FOTP/Leia/GS, etc, in combination with assisting threats, most notably QGJ that need a adjustment. If a 50% damage buff on an assist (2 high damage attacks in one turn) isn't totally imbalanced given the current damage potential from these 7* teams idk what is.
