Ideas
Been trying to do the entire Support Specialist challenge series, and the final stage is currently incompleteable.
Part of the challenge requires you to "Deal damage with the Incendiary Airburst Launcher as Support", however, the Incendiary Airburst Launcher damage you do doesn't track properly. I can camp it for full games without gaining any progress.
I also believe the weapon itself is bugged (or just very undertuned) whenever you fire it, as you almost have to hit point blank shots for you to even do a little amount of damage, and even then the cloud afterwards rarely damages people in the area.
I just went on XFCP and farmed it with bots. It's way easier if you are on the defending side at the first capture point, since they usually congregate on the hill, so you can just blast them. It still took FOREVER.
I did the same for the Assault incendiary shotgun and the grenade launcher challenge. I know that DICE wants us to gradually work on these as we play throughout BF6's supposedly 3-year life cycl,e but some of these items don't really fita lott of people's play styl,e and trying to farm them oregularrmal match is a pain in the **bleep**.
