Ice Splitter vs Fake Shot?

So this is kind of a different question than your normal Ice vs Fake.

Im lvl 70, with 37 SP (xP) and im wondering if its worth it to Max Fake, now that ill be in my 3rd job using Ice...

I really never used it in training, but will it be useful later on? I dunno, maybe on Ice monsters of Time Temple? Ive used Granade alot more...

Also, is it truly recommended that Wings and Recoil are maxed? Cause ive kept them at 7 (Wings) and 15 (Recoil) cause I like their distance... but dunno how useful their maxed.

All help apreciated
