Display MoreDreameR68 I agree with this mate and I am up for 1st option with a bit change.
If you have 100% anti CC and if they use RP duration, that RP duration will only last 1 sec, that is whole CC will last 1 sec.
That is, I will take SK Fear as example as you put it there, if you have 100% anti fear, it will only last with RP duration 1 sec.
Reason for this is that even if you use 100% CC, skills won't be useless but will be good as "interrupt".
Watchout how everyone will losing 1rp for 1s of fear or confusion.
