Pokémon X and Y Playthrough Discussion

Yup, EXP Share is 100% guarantee you'll overlevel the entire game since instead of only 1 getting experience it's your whole team, constantly, so in some cases you can end up with Pokemon that are overleveled without even USING them (Event Blaziken + EXP Share)

I didn't use it, and never made a point to grind either and I was weaker than all the Elite Four and the Champion when I got there. The Champion would have EASILY swept me if not for me using Toxic on their strongest Pokemon that slowly ate away at it while I revive-stalled. Best experience.

I had it on for all of Y. But for X I'm going to catch one pokemon after each gym and wonder trade it once, then use the resulting pokes as a team. Including the starter. And no exp share. Should be interesting to fight the E4 with 6 caterpillars.
