I did a little bit of this today. It gets redundant fast, but I did get to level 21 by finding blue engrams.
After finishing up story mode I can kinda see why some could be disappointing with the story. There are many things left unanswered. But I expect that to be revealed in the expansion pass. The game is fun as hell playing with friends.

My least favorite enemies
1. Knights with Swords - They're straight up assholes.
2. Minotaurs - They are assholes too, the mutli-teleport to get close to you and avoid your void weaponry is crazy, but they aren't as scary as sword knights because they arent as fast and don't chase as aggressively.
3. Cloked Vandals - Just an overall nuisance. On their own they aren't bad, but they normally show up when you are tied down by something bigger. They are great at dropping your shields when you don't have time to look for a distortion in the distance.
4. Champion level Hobgoblins - They can one shot kill you.... nuff said
5. Any Elite Cabal - They love rockets....
