Which sheet are you looking at? New roots and snares, on sheet 2 (for me, anway) has the new nanos, where all roots and snares have a seperate PvM/PvP function, and all have a cooldown.
The nano you're referring to, Greater Restrict Movement is gone and replaced by Engrossing Elocution, which has a 100% NR check and 10 sec cooldown.
I think you're looking at the sheet containing the old nanos. Nub <3
