I tried various builds with 100% boon duration and can't upkeep Alac if I have to do anything else, like heal. Tied using Feed from Corruption but you don't get barrier when you've removed all the boons so after 30 seconds that trait is pretty much useless. Then tried Sandstorm Shroud and that was a bit better because you get an extra 2 seconds of Alac out of it but still not enough to keep it up 100% without spamming all your skills. So you made it so Alac is generated when scourge gives barrier and then took all the barrier generation away. You left manifest sand shade which you have to spam every 8 seconds and only gives 3 seconds of Alac with 100% boon duration, sand cascade which you have to spam every 8.5 seconds and only gives 3 seconds of Alac with 100% boon duration, Sandstorm shroud which you have to spam every 17 seconds and only gives 6 seconds of Alac with 100% boon duration. Then you have a total of 2 punishment skills that give barrier, Serpent Siphon which gives you a whopping 3 seconds of Alac on a 20 second cooldown with 100% boon duration and lastly Sand Swell, a teleport on a 35 second cooldown for another whopping 3 seconds of Alac with 100% boon duration. There are no weapons that give barrier for any Necro spec. So if you time everything right and don't tried to do mechanics or heal you can probably get 100% Alac uptime but just don't try to do anything else.
Now let's talk about healing. All you have is regeneration. Not actual heals for your squad like Ele, Mech, Druid, Scapper, etc. And the regeneration you do have is substandard compared to Druid and Ele. Part of the reason Scourge didn't need direct heals is because it had barrier for mitigation but that was taken away.
Ele gets 10 seconds or more of Alac with overloads and the duration stacks so you can build it up pretty quickly. Mechanist gives Alac on barrier but the duration for crisis zone is 10.5 seconds and then you have barrier signet, barrier burst, and mace 2, which is part of the normal rotation, to fill in the gaps with barrier to keep it going pretty easily. Both Ele and Mech can also either heal or do DPS when giving out Alac.
It would have been nice if you actually tried to use the spec in actual gameplay before releasing changes like this. Scourge is useless for end game content. Can't do DPS, can't heal, and can't provide Alac. It would have been better if you just told everyone that you are removing the spec instead of just destroying it and leaving it in the game.
If there was a test build that shows these changes actually are viable, I'd like to see what your QA team and testers came up with because I'm at a loss to find anything that works at this point.
