Yes please ban Regina, either that or (preferable) reduce semi-evo 4* damage to 4. Decks with the 5* are more beatable than with the 4*, and 7 gap is usually enough to 2 round win
Also Barbacoatl for similar reasons, the 4* semi-evo with 8 power plus life gap potential plus wall-y ability are too strong together, though the 5* is balanced
Instead of #Ongh Cr my preferred Jungo 5* unban would be Troompah, much more vulnerable to losing the ability but also much more fun to play
Most every low star DR option are banned, even besides usually doing just a bit extra (like artus stopping jungo life on top of DRing) they often are picked so consistently that it stagnates metas and centralizes what cards can and can't be played. I remember being in literally every single Skeelz half or mono because nothing else had the DR for the cost besides Spiaghi who was even more prevelant that he'd be the single splash over their own clans DR. The only ones that are still around are the Atk clan ones where it's typically a defining feature of the clan or the really high star DRs, so that it's at least a give and take of advantages.
