I wanted to take a look at the type chart and see what I would change. The goal was to strengthen some types that are struggling a bit (Ice, Poison, Bug), and potentially pull back on some that are a bit too strong (Water, Ground, Ghost). It's easiest to see the differences if you can toggle back and forth between images, but here is the full list of changes as well as a short justification for each one:
Water attacking Ice: 1.0x –> 0.5x (They are the same element, just different states of matter. Since Water resists Ice, I feel that it is fairy to have it the same reversed).
Poison attacking Water: 1.0x –> 2.0x (Pollution is a common reason for water to be considered "unhealthy").
Ground attacking Ice: 1.0x –> 0.5x (I see this as a similar situation to Grass, where the ground shaking/moving doesn't really matter to Ice/Snow.)
Psychic attacking Bug: 1.0x –> 0.5x (Bugs generally don't have complex brains so it makes sense for psychic powers to not do much to them.)
Rock attacking Ice: 2.0x –> 1.0x (I see it as Ice and Rock can both affect one another equally. Rocks can smash weaker Ice, but glaciers can also carve out valleys in mountains.)
Rock attacking Fairy: 1.0x –> 2.0x (Similar to the reason that Steel is strong against Fairy, I see Rocks as large, crushing objects that would work well to hurt a Fairy.)
Ghost attacking Grass: 1.0x –> 0.5x (Plants do not really have a reason to fear ghosts/undead. In fact, plant-life is often used to convey fear with dark forests, graveyards, and dead trees.)
Dragon attacking Ice: 1.0x –> 0.5x (Dragons are supposed to be weak to Ice, I feel it just makes sense to give Ice the resistance it needs. However, the goal here is to also give defensive Ice types (Avalugg, Walrein, Rotom (Frost), etc.), a use-case to wall against strong physical Dragon-types.)
Dragon attacking Fairy: 0.0x –> 0.5x (I personally never liked how, in order to fix Dragon being overpowered before Gen 6, they just introduced Fairy and made it immune. It's fine to resist Dragon, but I feel that this change, along with the one above this one, puts Dragon in a good spot without giving Fairy an immunity.)
Fairy attacking Rock; 1.0x –> 0.5x (Essentially a follow-up to Rock's new strong match-up into Fairy. Rock is tough and rugged just like Steel. Maybe a stretch but Rock really needs love defensively.)
