I quite like the new interface so far, but we'll just have to see how it is when it's finalized.
3. Nami is fun. REALLY mana hungry, but fun. Her ult is good, if a bit awkward. Both her Q and her ult take some getting used to as far as the timing and aiming goes, but that's the same for almost any skillshot. And despite how well some of her abilities scale AP, I'm pleasantly surprised that she doesn't carry incredibly well compared to other AP carries. At least, not that I've noticed in the whopping 2 games I've played as her.
