I like these twists in PvP myself. If a stealth class can sap (8 sec) and capture the node in AH(6 sec) it makes for a more interesting match. It is the same with huttball to me with a Jugg/Guardian interceding to a stealth class.
They both seem so wrong but it makes those games more interesting, no?
You need some skill to pull it off on AH against a decent defender. It can be shutdown with 2 defending players.
On huttball it's a matter of 1-2 GCD and the jug is already in position to score.
