Valoran needs a thief Champion

Champions like Janna, Talon, TF, and Graves have been thieves in the past, but never kept it as a lasting occupation. Well, if the Elder Scrolls series has taught me anything, it's that the life of a thief can be quite adventurous, dangerous, and profitable.

Since the IoW has been retconned out, a thief is now a more viable addition to the roster. Anyone agree with me?

EDIT: Here's a story for one I'm using for a Champion Concept. It's rough, so take it with a grain of salt.

Ritz was originally a small-time pickpocket who stole money and food to survive, but she was clearly talented. One day, she ended up picking the pocket of a master thief named Legault, who happened to be the Guildmaster of the notorious Shadow Guild and was called the King of Thieves by many. Legault, impressed by her skill, caught up with Ritz and invited her to join the guild, and trained her personally in the arts of thievery. Ritz took to the lessons like a fish to water, and grew to admire her mentor. Through Legault's training, Ritz soon grew into one of the best thieves in the Guild.

But when Ritz was only 13, Legault passed away. Legault left in his will that Ritz was to be his successor, which was met with skepticism by the other Guild members. To prevent the Guild from devolving into a power struggle, and to prove her skill to the Guild, Ritz took on a highly dangerous job to steal a relic from The Black Rose Society in Noxus. Ritz managed to make her way to the relic, but was caught red-handed by none other than Leblanc, leader of the Black Rose.

Instead of killing Ritz, however, Leblanc used a spell to probe into Ritz's mind, and learned she was to be the next Guildmaster of the Shadow Guild. Seeing an opportunity, she allowed Ritz to escape, and even gave Ritz the relic as a "gesture of goodwill". Knowing she had to accept or die, Ritz took the relic and fled.

Ritz returned to the Guild with the relic, and the Guild decided that Ritz would officially become Guildmaster once she came of age. However, Ritz was left feeling unworthy of being leader, as she was essentially given a hand-out by Leblanc. Wanting to truly prove herself worthy of being Guildmaster, Ritz now seeks to pull off even more daring heists, while also seeking a way to turn the tables on the Black Rose and Leblanc.
