I'm definitely in the same boat. When I first started out all I was into was mma. Then recently I've started to transfer my obsession from mma to grappling with a gi. Whether it be judo or bjj, the gi game has most definitely taken the top spot from mma.
I think part of this is due to the unfortunate difference between people that train with a gi, and those who study mma. Hopefully further down the road mma will become as acceptable as traditional martial arts.
