Well the truth is the 1st and and 2nd gym is little bit hard but not really that challenging they can easily be encounter if u have the pokemon that have the advantages to those gyms. Most new comers that are having a hard time are those who pick charmander as their starter. They don't know how to encounter those gyms and thats what give them a hard time. I easily beat Brock using squirtle and Misty with pikachu.
