The primaries were not game breaking in year one, it was a heavy weapon that made pve miserable for players that did not have it. Maybe the primaries were broken in pvp, but that will always be broken. Even if you would take away voc solar damage, its still way better that the scout rifle from ttk raid. The element damage on primaries were a plus, that made raids and nightfall grindings more bearable, no there's no point in the grind cause the gear sucks in year two.
