[quote]Solo Caldera Master and make it B+.[/quote]
You don't get anything good from those since reset. They just drop bog standard low tier rewards. To get anything good you gotta do the things with a disintegrated engram on it, thata where I've been getting the tasty loot, and as I said, they removed it from caldera and k1 at reset.
some cant get b+ if you cant complete it its better to go for the sure thing then waste your time failing. i go for b. this grading system was a big mistake. if you are losing players you need to make the game easier not harder. i sometimes go for a c+ and get a b. it takes me 13 minutes sometimes on master k1 logistics i have to run away a lot of times and kill adds that will kill me. they dont allow getaway artist which makes it harder and thats the reason why they dont allow it. only the elites are welcomed everyone else is a second class citizen.
