I actually did quit Pokemon for a while. There was so much to do, mostly thanks to all the IV BS, that I decided not to get involved with Gen 5. Gen 5 itself didn't look interesting to me either. Add to that a third Fire/Fighting in a row and I was done.
I nearly quit last week because a Clefairy killed me badly. Was the trainers only pokemon, and he took down my whole squad of pokemon. I just stared at the screen in disbelief for 10 mins, then shut off the game. About five days later, I manned up to play again. (And this time I switched Gigalith for Lucario, and Force Palm'd the ever loving heck out of it.)
Sic vis pacem, para bellum. Don't make me HM01 you.
