>>7858Choose 6 that you think are cool beforehand, don't worry about "better" or "worse" for PvE.
Usually, it's pretty late game by the time you get the 6 you were after, which leaves plenty of room for dicking about with 'mons you wouldn't usually bother with.
This gives you enough experience to know what's good or shit in the future, and should leave you with a pretty solid team come the E4.
In summary, calm the farm and save the autism for competitive play.
