How is it now.
In Pokedex > Wild Locations of a given Pokemon we can see a column that shows Rarity aggregated into groups like (Common, Uncommon, Rare)
Suggestion.
I suggest that the Rarity is shown as percentage as well as it is divided into day / night encounter rate.
(I made up these numbers, I don't know exact encounter rates)
Motivation
On multiple occasions it occurred to me that the Common, Uncommon, Rare groups are too wide and that we lack night encounter rates.
For example during last wingull catching contest some people went to Slateport to catch their wingull although it turned out later that encounters at route 103 are waay more common. Pokedex shows common for both locations, though which is kind of misleading.
It's the same for rare Pokemon where things that you need to look for 15 min to find one (like togepi, clefairy, mantine, etc.) are labelled 'Rare' same as some other things that you meet every few Pokemons (Minun, Plusle, Illumise, Volbeat, etc.)
Similarly for day and night. Pokedex currently only shows daylight encounters so for night encounters information is very misleding. For example during day the route north of Pallet town has many pidgeys and rattatas. At night, though, there are mostly or only caterpies. Pokedex won't inform you about it atm.
