I hadn't played in a couple weeks, so I missed a few patches, Blank. ;p
Fiddlesticks I actually really enjoy using as a jungler for LOLSURPRISECAWCAW. The issue I have with him is he's incredibly easy to counter-jungle with almost any other jungler - he's extremely delicate until at least around level 7 or so. Makes me nervous using him in the jungle, particularly since I tend to play solo queue where you will almost never have protection from your team in the early jungle. He feels like a liability. :| Gangplank can at least run away from things.
My favored champions:
Vladimir (though I don't use him in PvP often - doesn't feel effective enough compared to other choices)
Teemo (though I build him more AS/AP Tanky Hybrid - Malady, Wit's End, Bloodrazor, Frozen Mallet, etc.)
I don't really tank/support much, though. Never feels like I'm contributing much to the team, particularly when we're losing all the teamfights and I'm the only one not dying but can't do anything about it because I can't kill anyone who's left after the fight. :| ...well, not as support, anyway. Singed can run people to death if I've had opportunity to farm him up enough, but he's squishier than most people think before he gets his farm.
Reducing minion damage actually helps out squishies more than tanky dps. Tanky dps are the ones that can dive through minions and towers and ignore the damage already. Squishies are the ones that have to be careful with their harass so minions don't kill them. ;p
