What does this mean?
- Attacks that are the same type as the Pokemon using it will do 50% more damage. (This was always supposed to happen, but was broken)
- There is usually a variation of 10% in the damage dealt (between 90% and 100% of its max potential damage). This will be changed to 15% (between 85% and 100% of its max potential damage)
These changes will most likely be happening over the next 24 hours.
Remember STAB will also be applied to your opponent's attacks, so some gyms and trainers may battle you more aggressively.
P.S: I'd also like to apologize for my various posts on the forum saying STAB was working correctly in the game until now
