Cause i've played PokeMMO and the normal games 100's of times over already. I just skip the story so I can get to breeding/competitive play where I get most of my enjoyment. This system makes you train multiple Pokémon cause you can't just wing it with 1 anymore, and that's not bad cause it fixes a problem in an 100% online game that the normal games don't have. All I'm saying is for me, personally, this system sucks the way it has been implemented right now. I've played the B/W, R/S/E etc. stories enough times throughout my life to know what happens by now, I just want to get into the new region with a bunch of friends, we get to the ending so we can help eachother breed the newly added Pokémon and we start fighting in Pvp. Now I have to spend time training a team to at least level 50-ish for the 8th badge in Emerald etc. just to throw that team away again when I'm going to breed proper pokemon for my Pvp team after the e4. Just personal preference.
