The following changes have been made based on analysis of the latest GAME_MASTER file.
Dodging gets Nerfed
"dodgeDamageReductionPercent": 0.75
Confirms dodge reduction is 75%. A nerf to dodging. If our speculation is correct, this means that you will take at least 25% damage even if you fully dodge a move. This makes defending gyms a little easier.
Move Changes
Niantic has once again updated the movesets of various Pokemon. Checkout the list below to see what has changed.
Note: Move changes only affects newly caught/hatched Pokemon, so far. Existing Pokemon movesets are remaining the same, for now.
What does this mean?
Muk is offensively better.
Golem becomes a better defender but a worse attacker.
Chansey's defense improved, but still not a viable defender.
Gengar improves with Sludge bomb, but he is still weak.
Gyarados only has one quick move? Loses dragon breath, severely hurting the Dragonite matchup.
Porygon's defense improved, but still not a viable defender.
Seel gets a huge nerf.
