I have read most things here, and came to the conclusion that im a very easy going guy, since i dont have such complaints. For people complaining about grind, it will always exist, because even if enemy trainer level growth gets lowered, grinders will always be grinders. At least now they can't abuse their grindo-mania so much. To be honest i don't remember myself grinding much, EXCEPT at the early levels in the alleys of peridot ward so i can have at least 5 pokemon level 15 before team meteor event + gym. I remember the low encounter rate testing my patience.
Apart from that, this is not a complain, rather a suggestion/thought. In a game that is so innovative, i would really like to see an alternative thing to weak HM moves like cut, rock smash, flash, etc that does not rely on us having 5 main pokes and an HM slave most of the time. Like, Florinia handing you a machette key item instead of having to have a pokemon with cut, have a lantern instead of flash, etc.
Oh and i guess i was a bit disappointed after learning of the fact that certain gym leaders used to be harder in previous episodes. Was thinking of downgrading to previous versions before facing them for a bigger challenge!
