If I recall sap is now passively a 10yd or so ranged ability. No need for talents or glyphs.
While I'm not against making sap viable in pvp, including against mounted enemies, I still don't understand why can rogues easily sap a hunter in the middle of its flare or a paladin in the middle of its consecration or any other AOE. What is the point then?
Back at the beginning of the game, rogues had penalties for their stealth mechanic which is arguably one of the strongest mechanics in pvp in any game. Stealth reduced movement speed, if they got too close you could see them, especially hunter's tracking ability. But now stealth has zero penalties, you can even move faster in stealth if you wish to pick a talent, you can shadow dance, teleport and all that. I'm not against making rogues more mobile or easier to play. However I do mind when the stealth mechanics becomes a mechanic with no downsides and barely any possibility to break them out of stealth except for demon hunters.
Sap at least should not be able to bypass someone standing in the MIDDLE of a hunter flare or consecration. What is the point of those abilities if they are useless now against invisibility?
