@Meddler: Is Trundle going to be the only Champion who "makes Zerg Creep"?
Trundle's Frozen Domain is the only skill in the game so far that gives a terrain advantage, specifically to Trundle. While a very novel mechanic, I feel like it needs to be done more than once in League.
When looking at Zerg Queens in SC2, they basically "poop" Creep Tumors that give the Zerg speed advantages and essentially free vision, though it can be cleared away if your opponents use detection. Do you think a "Creep Tumor" could make for an interesting ability, or would it be inappropriate for a MOBA?
