The role of luck in a MTT will change as the field gets smaller and smaller, because the blinds keep cutting away at your M.
The way you read situations changes as this happens, because betting, calling, shoving ranges change as # of BB in your stack decreases.
You are right in that winning a MTT probably takes more "luck" than having a winning session in a ring game. As you approach the end of a MTT, you have to get more of your stack in, in increasingly marginal situations.
Shifting over to cash games might help. Luck is there, but the blinds don't increase, so the role of stack size isn't as wildly fluid. You still have to play a short stacked player differently than a big stack, but the blinds won't be a dynamic factor in that over time.
