If so, the area indicator either needs to be on the non-MTX version, or it should be removed from the MTX version.
I was going to say the same thing. In the non-MTX version, there actually IS an area indicator, but it's so faint that you'd never notice it during the chaos of a mapping session.
Go into a dark hideout/map and charge up. You'll see what basically looks like shocked ground around your character without the MTX. I'd like to see this be given a noticeable lightning border of some kind, because without it, there's no way you'd ever see it while surrounded by mobs.
