Schreck Pgrens have a choice, you dont have to upgrade them with g43 and schrecks. Why would you do that anyway because G43 have bigger priority than schreck so it will nerf your AT capabilities even more.
There is little reason to upgrade with G43 (other than interrogation), but the problem exist for PGs even without them (it simply made worse with them). The problem does exist also with shreck S.T. who actually do benefit from g43 and can drop it easier or be left with out if the lose the shreck entity.
The issue with Shreck Pgs, is that one has to consider retreating after losing 1 model or risking dropping a weapon during retreat...this imo is contributing factor to less PG shreck Blobs.
In the end of the day we can agree to disagree. Imo not picking a weapon you dropped is mostly bad play (accept rng squad wipes, and sometimes dropping weapon on retreat) and thus I see no problem with being penalized for it.
In addition being able to double equip weapon is serious perk and again I do not see a reason not to have draw backs.
If perceived this an issue I would have to perceived the VG not being able to pick up weapon a more serious one and I do not perceive it as an issue.
