Good concept, I hope the lessons learned from this will be reflected in the next iteration of the event. Scoring bugs aside, they need to make sure it's accessible to more players than was the case as the start of this event, and relying on the rare HVT spawns in Solo Ops is very unenjoyable. That said, I wish this event was the exclusive way of getting holofoils for the featured weapons, rather than them each having their own week that offers a [i]different[/i] holofoil. What made the original Onslaught ones special was that they were new and rare, now it seems that every event is going to have a special version. That's alright if you're chasing it a few times a year at most, not every 3 weeks, especially when some are only available before most players are a high enough level to get better reward tiers.
