You need spell penetration to do your CCs, mainly Cyclone and Entangled Roots. Both spells are Nature-based, so they can be resisted by most if the opponent(s) have resistances to it (such as Blessing of Kings and Mark of the Wild). If you're doing pug BGs/world pvp, then around 125 is decent. If you're doing for arena/rated BGs, you might want to at least hit the soft cap of 170 (or hard cap it to 220 depending on the comp, but I don't think it matters to Feral as of now).
