After hearing a moot complain about one of their favorite 'mons being worse in their original form compared to a newer regional form they bring up a valid point:
Regional forms aren't exactly a buff to older pokemon like some people say
You can't switch a pokemon's regional form. A Meowth caught in the Kanto games can't change to Alolan Meowth. Your only option is EV train a new Meowth from scratch, and make sure it's an Alolan Meowth, too!
Compare that to Mega Stones where you can simply swap hold items and you can improve a pokemon no matter what generation you trained it in. With one Slowbroite, You can Mega Evo a Kanto Slowbro, a Johto Slowbro, a Hoenn Slowbro, or an Alola slowbro. The region doesn't matter, how long you've used it doesn't matter, what game it came from doesn't matter - if it's a Slowbro, it can Mega Evolve.
See the issue now? Regional forms can't be interchanged like changing a 'mon's held items so they're like a soft reboot of a pokemon rather than a true buff.
Also something else I've noticed is that regional forms have slowly been designed as "definitive versions" of Pokemon lines rather than being designed like "alternate playstyles"
In Alola, not much changes between regional forms besides move/ability pools to accommodate the different typing and maybe a minor stat change.
But when we get to Galar, we get all sorts of wild stuff added to regional forms, but hardly any equivalent buff for the original form
Galarian Zigzagoon gets a third Evo, while Hoenn Zig is still two stage.
Hisuan starters get cool signature moves and beneficial Hidden Ability changes, but no similar move/ability addition added to the home region forms (that aren't Decidueye).
Sneasler. Just Sneasler as a whole.
The most balanced modern regional is arguably Clodsire: same secondary and hidden abilities as Quagsire, same # of Evo stages, both forms seem to hold up gameplay wise. More regional forms should be designed like it!
If newer regional forms have more than the base form, give the base form the same treatment
If Galar Zigzagoon can get a third Evo, the original region's Linoone should get a third Evo too.
If the newer regional form has a better stat spread, update the home region form to have a stat spread identical but with more emphasis on what the regional's stats lack
And yes, if Sneasler can have Dire Claw + Poison Touch, Weavile should get a "frost claw" equivalent and a "freeze touch" ability too!
