One recommendation from me here is to spend your jewels on single element boosted gacha, that often happens between events (if you indeed want to play one element).
Do you need to play all elements or mostly your main one + the one countering the one which counter your main element?

In the second case, the point stands, there is no advantage trading a rudra for a Belial without fire or thunder SSR.
