For me its the lovely Ivan - i_PullDaStrings. This little weed uses his 'paranoia' as an excuse to hide the fact he needs control on tengaged, whether in a game, or over people in chats, and when his control lands him in a successful spot - i.e. finals in a game, he acts like he's won an emmy or something. He's the prime example of somebody who could do with putting more energies into his RL, than he does here, because his balances are clearly 'off'. He manipulates well, but what is the point - these are just games, but he overthinks them, and when he makes finals, he discredits other finallists completely. My RTB multi saw this first hand.
Plus, MIGHT i add that he's the first person to kick up a huge fuss when things DON'T go his way...I suppose like many on tengaged.
