I like the changes to stealth, but they feel half done. It will be good to have a much clearer definition of what skills can pull you out of stealth when casting or having cast on you. It's reasonable to buff the detection areas of the counter spells.
But it would be nice to mirror the behaviour of NPC's with detection abilities, so that when stealthed you get an aoe indicator of the detection range (seeing as different abilities and morphs have different ranges) and the swirling lights that indicate when you are stealth blocked, so you know when you can return to stealth. It would also be kind of fair if detect could be purged. Given that stealth is the NB's main counter to incoming damage, it's very easily countered and will be pretty much guaranteed to be countered next patch as every group will have someone who can counter stealth assigned to do so. Yet there's no counter-countermeasure at all.
