The Warden class in the Lord of the Rings Online (introduced with the new Mines of Moria expansion) is, all things considered, a blast to play. A capable jack-of-all-trades class, rich in tactical options. Not a class for those who prefer their combat to be a bit mindless, the Warden keeps you thinking.
The biggest downfall of the Warden is probably hubris.
You see, the Warden is capable. Very capable. Durable in a fight, with a mix of melee and range attacks, and a variety of support powers, when they come up against opponents without special attacks (poison, stunning and so forth) such as orcs or brigands, Wardens can quite comfortably take on foes up to five levels or so above their own. The downside of this is that it can often lead you into trouble.
