Not to sound rude or anything... but, any Yuki without Ice Rain is fail.
It's one of Yuki's highest DPS skills, there are absolutely no reason why you would not want to get it.
And well... you could save some points if you just leave the skills at their 65+ boost, since after that, there isn't anymore huge increase.
I came up with something like this after though.

There is 1 point left, which I took out of Max MP Increase. The 100 MP is not really useful IMO, but you could just put it back in :v
