When using one of the ranged weapons, there is no sound or visual effect. It could be usefull to know when a team player has done a kill and where he/she did it.
I suggest the same sounds and graphics for these weapons as the normal battles could be used.
really
you should if on adventure get pop up on your screen top left corner anyway saying buff been used, or they can tell you in chat.
to be honest i dont see the point in adding a sound effect in as it really isnt needed
then again i play the game with my laptop on mute anyway as i dont really need to hear the swords clashing in battles or silly music in background etc or the "whoohoo" when something been found or even the jiber jabber when you send men out seraching
