Being stunned by a ganking high level Ranger is a drag on PvP servers, so this is good news:

Firstly the way how crowd control and immunities work has been adjusted. This change now will cause players to break stuns, fears, roots, snares and charms when they have lost a certain amount of health. This should give players a fair chance to withstand these spells and fight back.

There will also be a change in combos, making them shorter and hence easier to execute, but they’ll also be less powerful.

The next game update is due in a couple of week’s time, and these new additions should already be on the Testlive server.
