Niantic has teased some information regarding a new feature which is currently in development for Pokémon GO.
A new "Capture Bonus" system will make it easier to snag that rare 'mon, and is all based around type. Catching several different monsters of the same type will earn you medals, which will in turn grant you a bonus which makes it easier to catch that type in the future.
In the examples given by the developer, catching 10 Poison-type Pokémon grants a +1 capture bonus, while having 200 Fire-type catches earns you a +3 bonus.
Here's the official statement from Niantic:
We want to give you a sneak peek of a feature coming soon to Pokémon GO. We are adding a new feature which grants a catch bonus when you earn medals based on catching certain types of Pokémon (Kindler, Psychic, Gardener, etc.). These new bonuses will give you a better chance of capturing Pokémon with a related type. For example, as you reach a higher tier for the Kindler Medal, your bonus to catch Fire-type Pokémon such as Charmander, Vulpix and Ponyta increases.
Trainers can work their way to a new tier by catching many Pokémon of the same type. If a Pokémon has multiple types, your bonus will be the average of your bonuses for each type. For example, Pidgey is both Normal and Flying type. Your bonus in this case would be the average of your Normal-type and Flying-type bonuses.
It looks like this system is still in development so we might not see it for a while yet, but what are your thoughts initially? Let us know by posting a comment.
