Hey Buffel! I know Gen 8 data has been implemented already. But I wanted to give some suggestions for buffing otherwise underwhelming Pokémon.
My first suggestion is giving Greedent Harvest as a Hidden Ability. Being a Pokémon focused on berries. It feels appropriate and also could be quite a powerful ability in tandem with Stuff Cheeks. No stat changes required, as I feel that would be enough to tip it over towards being a bit more desirable. Could be fun in Drought teams as well.
My second suggestion would be to give Orbeetle (or Mega Orbeetle, if that was a plan) an ability to increase the power of moves in Gravity. Pushing a niche move into something more usable. Whether it automatically sets up Gravity on switch-in or not is entirely up to you for balancing purposes. If not. Perhaps automatic Trick Room could make it a fun, viable strat for slow teams. (Permanent TR, perhaps?)
As a final suggestion. Change Boltund's Hidden Ability to Moxie and give it Strong Jaw and Defiant as it's normal abilities, and a little more Attack.
Not sure how much you've changed on these Pokémon. But some ability changes I feel would push their potential a bit more. Especially to be in line with your phenomenal hack.
Of course I'm unsure how much effort any of my suggestions would take. And I don't want to apply any pressure on you especially since I can only imagine how much work you put into this free hobby of yours.
Whether you accept these suggestions or have your own ideas in mind for all these Pokémon. Just know I'm super stoked and IE 2.0 can't come fast enough. But make sure to not let the pressure get to you, pace yourself. And have fun with it. Your "when it comes" mentality is something I can appreciate.
Best of luck in your future endeavours, whatever they may be.
