So much yes. If online petitions weren't totally ineffectual, I'd seriously consider starting a global one to pass around the internet to convince somebody to fix the arse-awful mess that is the GTS. I tried it again for the first time in 2 years the other night...within a minute I realised why I hate the bloody thing: because it's populated by 10 year olds and/or idiots who want an Arceus for their Budew, or a Shaymin for their Wooper, or a Darkrai for their Bidoof. Oh go to hell, the lot of you, and come back when you want to stop wasting my time and your own.

I was hoping they could have some level limit for each pokemon. Put the level available based on the minumum level you could be able to obtain that particular species. (ie. Lv.1 for Bulbasaur, Lv.16 Ivysaur, Lv.36 Venusaur, Lv.1 Palkia, and Lv.50 Zekrom). At least, there won't be any impossible request on GTS. I used to play all on my own during Gen IV, and most Pokémon I couldn't find, I have to rely on GTS. Nowadays, almost every request on GTS, even for Zigzagoon, want a Lv.9 or lower Zekrom or Reshiram.
I also hope they have more boxes for storage too. With all the gender differences and alternate form, even 24 boxes is not enough for me. (Well, I allocated 28 spaces just for Unown! ;p) Maybe they'll let us buy more storage box with all those extra money laying around.
