I agree, it felt like they put in extra effort on the owlbear so that they could be like "Well we have owlbear."
I wasn't sure I could learn how to mod as I am not computer literate, but the toolkit has been quite good in my opinion and I was able to release a mod I made that aims to buff some of the weaker forms.
For panther specifically, I increased its dex to 19, made its pounce cost a bonus action, and made prowl deal its 1d8 bonus damage at every level rather than just 6 and 7 (that bugs driven me nuts all year).
Feels a lot better now, but I also buffed bear, badger, and rothe. Now I'm creating new wild shapes, and have hyena and giant eagle about done and looking good. Hyena specifically is my pride and joy. I put in so much work on it to give it unique skills and it's own unique playstyle.
