>>59001622the biggest issue with G/F/W is that outside of the starters, Water is incredibly common, Grass is quite common, but Fire is quite rare.
And no, this isn't a problem exclusive to Sinnoh, although it is most severe there. Most gens just don't have a lot of Fire options.
There's one big reason I can think of for this: Fire type doesn't have a dedicated environment that's common. Grass and Water correspond to the most common places to find Pokemon in any Pokemon game. But when you think of a Fire type environment, you think of a volcano or an area surrounding one, which is pretty rare, and even the games that do have them are lacking in the Fire type department (Hoenn has like what, 3 fire types besides Torchic, and none of them are particularly appealing team members)
Unfortunately, there's not a good solution to this that I can think of, and it'd be pretty hard to replace G/F/W
