@Stolas I have good news for you.

I have an archived mod of this, which replaces one multi-class weapon.

If this goes all-class, I'm buying you a beer.

Well it couldn't be done with the existing animations available. Like I said below, we would have to make new animations and that reduces an items chances of getting in because it is more work on the TFTeams side that needs to be done. So most of the time it isn't worth the effort.

the right hand deals melee damage while the left hand does throwing, will this be difficult to do?

It's a neat idea but would require new animations. Those kind of kill a weapons chances right away,

nice. I have a suggestion. Why not make the baton and card be a melee primary and card throw alt fire?

vary cool
