Really need one. I have to be awake from 3 a.m (my time) till 6 a.m just to join guild war, ryoka attack and protect seireitei in the EU server.
And 3 a.m in US server for Evil Spirit. then 9 a.m-1 p.m for the rest of the event. At least i don't hv trouble staying awake. Just need a couple of hours 2 or 4 hours of sleep at least to stay fresh.
