The queen's wrath missions were kind of like this. (Destiny)

I think people's main beef was the reward system- Apparently, ascendant shards are supposed to be hard to get (LOL), so Bungie quickly posted a hotfix that prevented you from gaining those when breaking down the reward gear. So if you already had legendary armour in those slots, you were effectively getting NOTHING for doing these missions regularly. You could get lucky and snag a Sniper rifle or ship, but the odds for those to drop were way really low. I did ~60 of those missions, and I only got two of the sniper rifles.

Bungie could do wonders to eliminate this by only awarding engrams (and moving ascendant materials back down to blue status as they were on launch, so they can't come from legendary engrams anymore). Then, allow the cryptarch to change an engram to the type you want.

For instance, unless you are just starting out, legendary armor engrams always suck. You're not going to wear it, since you already have either raid or vendor gear. It can't be better. So al they are good for are materials and shards. But, if you can go to the cryptarch and re-roll it as say, a primary weapon engram, then now they are useful.

Awarding an engram for events like that now has a much smaller chance of being something you'd never use or want.
