It's said that Ganondorf got some pretty nice buffs. His C1 goes off much quicker, and is easier to charge as well (C5 apparently fills half the bar). Of course a slowpoke like Ganondorf benefits even more from Hasty Attacks than quicker, safer characters, so he might be the big winner of this update.
As expected, rescuing all four Giants grants you access to the moon (nine missions in the top-left corner). Beating the final mission there puts a stop to the countdown permanently.
There's one last 4000-KO skill that I didn't mention yesterday: Normal Attacks+, which increases the damage of all your regular and combo attacks. I'd say Hasty Attacks is better because you don't just get a DPS increase, but you also become a lot safer against enemy hits (especially slower characters), not to mention weak point gauge depletion. However, since you can have two 4000-KO skills at once... why not have both?
Majora's Mask and its fans clearly deserve each other. After all the bitching over the lack of Skull Kid, then the lack of Majora (being reminiscent of the crybabies who shat all over Ridley being more than a simple stage hazard in SSB4), my new favorite is all the whiners pissed off that Proxi is Young Link's mouthpiece and not Tatl. Since when has anyone ever given a fuck about TATL? Since yesterday, of course.
