I hate having them on my team since they can't fulfill their respective roles.
I had a game with 2 Javelins and 2 Guardians on my team.
I didn't want to press K, so I ran around with my secondary for over 4min on last obj chapel def. During that I got tap revived twice and then hid until I had some hp.
In the end I just flanked left through their spawn, passing half their team while killing the other half just to reach the ammo crate. Of course once I stacked my ammo full they rushed me as 4 and I ended up on longspawn....
Javelin's ammo armor definitely needed a nerf, but SD overreacted and overnerfed it.
Then releasing a medic with no healing.
