Riot, you stole my idea.
Coming back to League of Legends recently and checking out the new champions, I notice something familiar. Rek'Sai. A champion that has different abilities based on if she's burrowed or not... OH WAIT.
I came up with this concept over three years ago for a hero on a different, Starcraft II-based MOBA game called Storm of the Imperial Sanctum. After the game name was changed and the forums migrated, I had to repost my hero concept, giving it a different time stamp, but it is still in the year 2012, as you can see here: Slayer Dregenard
...I'm kidding, I'm not upset, I'm actually really happy to see something like this. I spent weeks on this concept and sadly it never saw implementation. Though my hero would play different from your champion, this still made my day. I like to think someone actually DID steal my idea and presented a modified version of it to the design team and they liked it enough to use it for this massively popular game.
