Ammo synthesis timer should reset with every strike, raid, mission. While in the strike list we shouldn't have to use a heavy synth at the boss only to go into the next strike with no heavy and have to wait for the 5 min timer to run its course. Also could we please have separate timers for heavy and special synth? With the last special nerf I find myself with no ammo except for primary at times and have to choose between heavy and special and there's no reason for that.
