I'm fine with having calls again as long as the volume of them can be controlled in the audio settings! Because all I remember the most about them was startling the living bejezus out of me because they were so loud! Especially in headphones! :P

And before ppl go. Oh Noes! then ppl could mute them all together and it would defeat their purpose! (yeah well for starters ppl should have the option to not hear them if they don't like them! Deal with it!)

Second you could make it so that the volume can't be muted but only turned down to 50% That way a player can't turn it off but listen to them at a more less deafening level!
