A) Only idiots think support is useless/can't carry. They're one of the easiest roles to climb with atm. The issue is that they're often not very interactive compared to other roles, making satisfaction really low, especially if you aren't ahead. That's why people don't like support.
B) New support itemization is definitely overloaded. However, its the current state of runaan's+IE+Warlord's that makes that an even bigger issue than it should be. Generally over-tuned damage in the game right now almost necessitates it, though. The game's heading downhill on that front, and if Riot doesn't do something about it, the game will crash and burn.
C) A lot of posters like you are also the reason they pay relatively little attention to the forums.
