Just beat the league and I'm a bit underwhelmed really, so much as I'd call it the weakest league out of every game so far.

4 Pokemon per member is a pretty pathetic offering, and the only Pokemon the champion the had which didn't get one hit KO'd was her last one.

I know I'm getting older and I did have about a 10 level advantage simply because of how experience works in this game, but I'd at least expect the best trainers in the region to have 5-6 Pokemon...

Literally nobody in the damn game has 5-6 Pokémon except 6 Magikarp guy, Diantha, and your rival. It's sad and pathetic. I've ranted about it here and elsewhere way too much to go into it again... But it is probably the most disappointing part about the game to me. It just made it too goddamn easy.

I completely agree. I though the gym leaders having 3 was pathetic enough but I expected more from the Elite 4.

I just remembered something that really bugged me when games like HGSS and BW came out, Shellos. They said in DP's pokedex that Shellos has a different color in different regions but they never actually took advantage of that, it annoys me.

If that to work all region would need to be remade so it includes that feature

If I recall, Black and White's E4 only had 4 Pokemon, too.

It was easy, but I didn't think it was disappointing...

After looking it up, yeah you're right. I must have forgotten about that.

Oh well, that's just another "too easy" complaint I can add to gen 5.

My biggest hope for the future is that games will have the ability to hold more than one save file.

I've beaten the Elite 4, I'm proud of my team & trying out the available postgame stuff but at the same time part of me also wants to just start all over again because it was so fun getting to this point.

Does anyone know how you start a supposed Looker subquest in the post-game

There's a second game you can go out and buy.
I mean, yeah, it's spending $40 to replay a game without losing your save data, I understand, but I really don't think they'd ever allow for multiple save files.
