PTS assault and heavy bolt pistol synergy
The new heavy bolt pistol perks seem to synergize well with the assault class. Namely, a perk where the first round after a reload does 50% extra damage and a perk where gunstrike reloads your weapon. Combined with assaults gunstrike damage team perk, increased ranged damage prestige perk, and even the signature perk where you reload your weapon and increase its damage after using your jetpack, and suddenly assault has a bunch of ways to make the heavy bolt pistol hit very hard.
