I would like to suggest, maybe it would be possible to implement this option to those Dominion Ops.

Instead of having Dominion Ops repeatable, The idea is giving the player the option to double or triple up on Dominion Ops (Quests), this could help with the lag around the Dominion Sergeant NPC, also within a big party the mobs tend to die so fast, one could be walking out to fight and complete Said Op, having to just walk back to Dominion Sergeant just to claim the reward. This could also help and stop players from just running laps.

Example:
Talk to the Dominion Sergeant, Player can pick one of the following;
Option 1.) Kill 5 Mechanical Menace. Reward 5,000xp.
Option 2.) Kill 15 Mechanical Menace. Reward 15,000xp.
Option 3.) Kill 30 Mechanical Menace. Reward 30,000xp.
(Cruor, Seals works the same how they are now.)
