Sometimes I think so..because there are so many moves and having teach my Pokemon HM's for obvious reasons take up move slots..especially if it's Defog and you can't un-teach HM's unless you go to the Move Deleter's house and that's just so much work and then having moves like leer or something that decreases the opponents stats can really help and I would really like to be able to have more moves..or something that HM's wouldn't have to be used so much so I can use/keep certain moves so er..maybe.

no way!! it becomes more difficult to battle opponents with more than 4 moves.
