/Ammo Command?

[Babekeke]

Or, just as likely, don't require a command, make it an automatic countdown when you reach 10 left. Then we all know not to Barrage when we only have 2 ammo left.

Hard for me to remember whilst I'm not on the game, but if you equip ammo via macro I think it automatically defaults to a 99 stack instead of a part stack? If so, with auto-sort switched on:

/ja "Barrage" <me>
/equip ammo <wait 1>
/equip ammo "Ammo"

As long as you keep on top of always having a spare stack, should mean that you never waste a barrage.
