I do not have a class swordman , so I want to know if any you have a skill that can attack from afar as an archer at certain times. 
why ?, because and seen some attacking that way , I took photo thinking it’s a Bot, but do not want to harm someone .
So before I asked … The name was normal and not one like this adfa23g12gwq …
I am sorry for my bad english 
Ranged attack as far as i can remember now is Shield Lob from Peltasta and GaelBog or something like that from Dragoon, basic attacks don’t do ranged attack.
If you want to know if it is a bot, lay an anvil and see if it will try to hit it multiple times.
Sometimes lag can make it appear is if someone is abusing the ‘ranged attack’ bug, when really their position just hasn’t updated on your screen.
If they do it consistently then they are probably abusing the bug. If it only happens once or twice, it may just be lag.
So you need to be careful when you report someone for that.
