With this is mind, we begin to see the flaw Harbinger needs blight to function optimally. Your elite provides more blight but at more than double the cooldown of the other elixirs. In order to get enough blight since each elixir removes 5 stacks and gives 10 except for the elite you need to run 3 to get 20 blight to match the burst damage of shroud. So they have to get it from their elixirs. So a harbinger can only generate so much blight while in shroud for those 10 seconds. Even scourge follows this rule to keep soul barbs up. You need to keep soul barbs so you are expected to be in shroud for 10 seconds and out for 10 seconds to maintain near 100% uptime of the trait. Necromancer builds require a few things for their DPS setups. So how do they do that? Well they need to run a few elixirs. Now this isn't an issue on its own but this means that they want to generate blight and spend blight to maximize their DPS. Harbinger is a quickness support or glass cannon DPS. They're not a tank, they don't have the tools for that either. So what happens with their builds? Harbinger isn't a healer they just don't have the tools to fill that role. Blight can only be generated by being in harbinger shroud or by using elixir skills. How are you going to generate blight? Much of the harbinger's design is centered around blight, primarily its damage which is interesting but we come in with a major flaw.

Right off the bat when trying to build a harbinger, when looking at builds and their traits and skills you're faced with a pretty important question.

But it also creates some issues which I'll go over. Before I really get into that I'd like to say I LOVE blight as a mechanic. More I'm going to discuss a very big flaw in its fundamental design which might turn people off to the elite spec. This post isn't about how strong it is, because no complaints here. I'd like to start out by saying that harbinger is still quite a powerful elite spec to run and it has 2 very solid builds In PvE and its fairly strong in other game modes as well.
