So, I played for a little while when it first came out, and chose the Pyromancer for my first character. I think I should have picked something different though, because the learning curve, for me at least, seemed a little steep, and after the first black knight slaughtered my guy like 20 times straight, I set the game down.
Now, a year later, I decided to start again, this time with the Cleric. Maybe the second time is the charm, because even though I die regularly, I feel like I'm moving forward with more speed, and am having less trouble with each battle. Plus, having healing spells in addition to Estus is nice.
