@WhoeverDesignedShen: So...why is Feint a shield?

Now, I know that abilities don't necessarily have to match their names (or else Decimate would be OP). But I do feel there should be a limit to how far off their name and effect is, or else what's the point of abilities even having names?

So without further ado...

Feint:

Definition: a deceptive or pretended blow, thrust, or other movement, especially in boxing or fencing.

In-Game: a purple magical barrier reinforced by crossed swords circling him

The idea of a ninja-tank is kinda weird to begin with. But when I read feint, I thought he'd be one of those "evade-tanks" in RPGs. But it turns out, that's not the case. He projects a shield using a technique he calls "Feint".

I mean, it's not really even a problem overall. But just one of those curiosities I've always wanted answered...like how does Cho'gath's Q works...or why is Shen a tank...or etc.

(also for anyone interested, watch a new champion spotlight and then watch Shen's...that monotone is amusing, "icy blast" level of amusing)
