Accessibility Markings to Show Directional & AoE

Essentially a skill like this would, optionally, have a mark to show you the directional or (less important but could be helpful) AoE type.
For example here you'd have (bad mock up):

(Because there are more rear attacks than face I just put the 'rear' as the top of the icon, therefore the sides are the sides for flank and the bottom would be 'face').
The AoE idea is simply right in the center you could have an icon for conal, line, or circle, as a separate option.
For jobs you're familiar with this is not helpful, but if you switch into a job you've not used for a while I feel this would help quickly and correctly pick up a class. Again though, it'd be an option- so if you don't want it then you don't get it lol.
One way to save internal real estate but show positional is to add a special border on the side of the icon that is the positional, like a gold line on the top would mean 'rear' (in the above example) or on both sides to show 'flank'.

Or perhaps rather than on the icon for AoE types there is an option to gently fade player conals akin to enemy attacks yet in a different color (how enemys have circular attacks marked on the battlefield), which could also help build memory easily (at some point you may turn it off).
Thanks for reading :)
