Well Reverse-Flash is Flash's arch-nemesis, so he needs to constantly be around to maintain that status. They've literally entwined themselves in each other's timelines, so both parties created the other.

Savitar was just a consequence of Barry's mistake and he's been fixed now, he didn't even exist before Flashpoint. Besides, he was a very divisive villain that not everyone liked. I wouldn't have minded seeing a bit more of Barritar though. Still not fond of that Megatron armored God Complex he was introduced as.
