Display AoE Radius While Targeting

I personally think it would be neat if the AoE radius of spells and abilities was hilighted on the ground during the time between selecting the spell/ability and selecting a target. I'm trying to think of another game that does this to give a good example, but I can't think of anything off the top of my head.

My bf has issues remembering which spells are cone AoE and which spells are circle AoE. Even I do occasionally. I think this would be a good (togglable) crutch for new players to learn the ropes of the fighting system.

good idea~ will be helpful .

Thank you. I think so too.
