Or just be lucky enough to still have 4 bags full of stacked Antonian Javelins. Question about that if they were stacked before the nerf and you move them to a different character or from bank to character or back do they stop being a stack?

For now.

Sneak SHOULD break when you initiate a throw. However you should be able to re-activate sneak before the thrown item hits your target and causes aggro. This will be patched in shortly I believe.

They stop being a stack. The night before that went into effect I had made like 20 stacks of them, all singles in the morning

forged javelins are fairly cheap to make.

You can use throwing axes, but that does mean a bit of inventory management due to lack of stackability and them not working properly with the ammo slot.

No way, as an enchanter I always want the monk who single pulls to leave to do IRL things so I can impress the group with amazing cc. :p
