Alright I'll bite! Let's throw some suggestions my way since I unfortunately have 30 days left on my sub.
Pvp - It's god awful and I'm a pvp fanatic. They have no clue how to do the pvp obviously and it's sad because Yoshi said he likes pvp but then makes it so casters can't cast anything. ._.
Dungeons - There's no rare drops from them, no point in running ones that don't give you myth/philos. Not to mention the level syncing and removing skills is annoying, which is why I REFUSE to do the low lvl roulette. And the dungeons are BORING they're small straight paths.
Crafting - Lmfao.
Gathering - ROFL!
Exploring - I hate running into a freaking loading screen every 3 seconds (exaggerating of course) one of the main reasons why I don't play a lot of console games. >.> I like the seamless feel, so much for that.
Treasure maps - I do them here and there but they are boring and pointless. Nothing rare/good will ever drop from them. If I wanted to kill random mobs, I would without the treasure maps.
Leveling all classes - Lol for what? I don't like the other classes so why level them? Okay just for shigs lets level other classes I don't plan on using. They are stuck at i71 since everything has a WEEK lock out and people only want i80 for freaking ifrit HM ._. it just sits there.
Level your chocobo! - Why? You can't really do anything with it. Maybe if there were oohh ionno elite mobs running around the world than yeah.
GC seals/rank - Dungeons drop/will drop gear that will be on pair with GC gear. So why level it? Oh yeah for the restat? You mean the restat that I'll never use because there's only ONE build for all classes. Yaapp
What is there to do? I log in I talk to friends I get bored. A lot of people say "Well log in to talk to your friends" why should I pay 15 dollars a month to talk to them when there's facebook/twitter/msn/skype/vent/mumble/etc
