When is 165 fcr worth it?

[slothkin]

I have a windy and it seems that i wasted a lot by invesing into the 165 setup. I can get 5 extra skill points without the 165% and in both pvp and pvm the slower setup with better skills always does better. When is it worth it to use 165 fcr?

it useful against casters in pvp.
