As far as forgotten subplots go, Cisco forgave Barry, Julian let Barry come back to the CCPD, Dr. Alchemy was defeated.

The Killer Frost subplot has been awesome imo I don't get why you don't like it.

Barry did have to go to the future, he wanted to learn Savitar's identity not see how Iris dies, he already saw that.
