Sadly already finished with Cosmic Exploration

Others might disagree, but the class A missions are way too hard. Gave up even bothering to try those after a time. Really disappointed.

The class A missions are hard, it's true, in the sense that you can't tune out and watch YouTube and mash macro buttons to do them. They force you to actually pay attention.

But I've managed to clear most of them on my alchemist so far.

I think a lot of the 100 penta melded crafters are opting to get gold on the A ranks, then swap back down to the less intense B ranks for grinding because you can just smack macros for those. (Even then, you better pay attention on what the durability and quality requirements are.)
