Keep in mind that I don't really play necro (I usually have to tank or heal and if not then I'll play Bard), this is just a complaint I've seen from atleast 10 other players in game, "why can't I see how well/badly my veil is holding up in battle?".
I don't mind not having anything for Curse because the visual indicator is so obvious, and since you can have 3 up, it's kinda spammy.
From a gameplay perspective, it's important to know how many Chorus charges you have if you want to use it in rotation (you can't always count your attacks), so this a legit request.
