I started a DEX build this weekend and brought him up to Anor Londo. I don't understand how people PVE with DEX builds - it's really hard, especially when the enemies start getting tougher. I can't imagine doing this pre-patch, when most of the early mobs were much stronger. It's fun running around all fast, and PVP is more fun, but it got so hard that I quit.
I then started playing my main again - a super tank. Brought her up to sl101, and now that the giant blacksmith sells sparkling titanite, I fully upgraded everything that I use. It's awesome. Co-oped a ton in Anor Londo, and beat skinny and fatty in NG+. Main, they hit HARD in NG+. Took me and two phantoms 5 times to beat them. Plus we kept getting invaded on the way to the boss door. It was super fun.
I also fully upgraded my P-flame, and got to level 2 in the chaos cov. I'm now prepared to fight the Bed of Chaos. It sure is nice to have that shortcut open.
