I've always been exactly this way too but I've been obsessively breeding and EV training over the last few months, soon to attemp some competetive battling so I guess that makes me a type E tooType B
I usually tend to lean towards using weaker Pokemon like Shuckle, Dunsparce, Mawile, Parasect, Sableye, Togetic, Wigglytuff, etc. I guess I just enjoy using them more, its weird. Not that I wont use strong Pokemon, but I never choose a Pokemon based on how strong it is.
Im not competitive at all, although I like to stay informed of the competitive metagame.
