Why does Teemo's W "Move-Quick" have a mana cost?
I always found that odd, because there isnt anything magical about it, or really impactful, he just moves faster for a fixed time, usually at an amount that most champs can outclass in a myriad of ways.
And even better is when you see abilities like Tristana's rapidfire for instance which gives so much more and yet costs 0 at all ranks.
