When I Wild Shape, I take a beast's STR, DEX, and CON scores. I [keep my proficiency bonus](https://twitter.com/jeremyecrawford/status/985927086643662848?s=21) and my INT, WIS, and CHA scores. I will focus this question on the assumption I'm proficient in Athletics, and I'm turning into a beast also proficient with Athletics. 

* I have +0 STR and +3 Proficiency, so +3 in Athletics
* Beast has +2 STR and a +4 bonus in Athletics

**What is my Athletics bonus now?**

On one hand, I keep my +3 proficiency bonus (so if I calculated things from scratch, I should have Athletics = +2 STR + 3 Prof = +5). On the other, tweets like [this](https://twitter.com/jeremyecrawford/status/558355703530672128?s=21) claim I should just use the beast's modifier, a +4, since it is higher than my Druid's +3.

But in this case, I'm now a creature with +2 STR, +3 Prof, and a +4 in an Athletics skill I'm proficient with. Can anyone confirm if I do or do not recalculate proficiency bonuses when I Wild Shape (or Shapeshift)? The rules are not explicit, and the way I've interpreted them is that you take the new STR, DEX, CON scores, and recalculate modifiers for your skills. After this, if the Beast had a better bonus than you now have, you then take its bonus.

Similar [question](https://rpg.stackexchange.com/questions/120511/does-gaining-a-proficiency-via-shapechange-let-you-add-your-original-proficiency), but it mostly refers to interactions with Expertise and other edge-cases. I'm looking for an (preferably backed-up by RAW or official comment) answer on whether I should recalculate my stats to accommodation my Proficiency Bonus with my new STR, DEX, or CON modifiers.

Also keep in mind, from this [question](https://rpg.stackexchange.com/questions/110570/are-attack-damage-modifiers-recalculated-in-wild-shape-if-ability-scores-changed), it seems a reasonable opinion that we should recalculate bonuses when scores change. But if you don't recalculate any proficiencies, how would this be affected? You could be cursed to negative STR and keep a massive athletic bonus.
