Bug or working as indend? Weapon swap changing on its own.

So I'm trying out weapon swap set.

Set 1 skele snipers 5 of them. For bossing. With other minions for muster arso is one of them

Set 2 Arso 4 of them.

in weapon set 2 if I spam my arsos command skill down to zero it will automaticly weapon swap to set 1.

I think its because when weapon set 2 runs out of command skill charges it will see i have an arso in set 1 and switch over?

Any ideas how i can get it to stop swapping?

thanks

How would I go about paying someone to test this?

I really want it to work.. but it automatically weapon swapping me to archers is annoying .

Or is this intentional so I can give up trying to get it to work lol
