I'm at 57 WHM and just remembered this cross ability. My Arcanist is only at 15 as I hate playin git and dread the thought of bringing it to 34 just to get this, but will if it's useful as it sounds pretty cool. Just thought I'd check though to see if it's still worth it? Second part of my question, I use Virus all the time, but I see some people have a Macro saying "VIRUS up on XYZ!" is that really necessary or helpful to anyone?
