>>45444259>If anything it's easier because your Pokemon get more exp off the gym leaders.Yeah no, I've played BW2 enough times on both vanilla and challenge mode enough times to say that's bullshit.
For example in the E4 the trainers have 5 instead of 4 pokemon, each one of them has a fairly useful held item instead of one of them having just a sitrus berry.
As for the gained EXP I really didn't notice that I was overlevelled at any point of the game.
Meanwhile the big boss of USUM, Ultra Necrozma, can be defeated by a pokemon by essentially just dabbing on it with prankster + toxic.
