If you use a skill or attack someone, their is a clear symbol and the combat starts.(hard to miss)
But if someone is standing next to you holding a sling, you can't see if he is aiming or just standing.
Can't we there be added a small symbol of a cross or something?
I believe that a to large symbol would make you to easy to detect.
But something small, that you would only notice if you looked closely at the person.
I tried to search the forums for a similar post.
I didn't find any.
If there is, i apologize beforehand for not searching well enough.
