Well, not to say what you say isn't true, but I find in matchups vs magic damage, you end up generating a lot of void energy really fast, as it appears to be pre-mitigation damage that's generated as void energy, which is generally when you would use Dark Shield to start with, if you take magic damage at all then void energy is a much more expendable resource, even by ticks like on-hits can generate sizable chunks.

usually 2 or 3 magic attacks can charge your void energy to full, after that its a matter of using Veil Off, which is a huge buff for VAs to begin with, then there's also the buff that lets VAs keep half their void energy at that null damage cost.
