I thought of this aswell, but it would make bug types more mandatory for your class (Unless you really really want to be a bug catcher) and makes it less 'free'. Unless you can have multiple perks at the same time... Feels a slight bit OP.and leeloozeteBug Catcher, Lass, Ace Trainer, Hiker, Leader, Elite 4, Champion, Picnicker, Youngster, Rival, Elder, Sage, Medium, and a whole lot more. I just listed those off the top of my head.
think about this.
PERK SYSTEM!!!!!!!!!!!!!!!!!!!!!!!!!!
every 'class' has a small benefit to it. like a bug catcher class has the perk of increased damage for bug types a small boost in exp AND instead of 2x damage from fire it's 1.5x????
i really think perks would make the games sooooo much more interesting
