PvE
The Chaos Chosen is hard to beat in PvE environment. They tend to solo quickly with their high tolerance for damage and ability to enhance their DPS through their different auras. Their auras can enhance Chosen's damage, resist effects or even enable them to heal themselves for small amounts. Auras can also buff their group members, so they are quite an asset to any party.

RvR
The Chaos Chosen's preferred mode of combat is up close and personal. The combination of their ability to soak damage, do a decent amount of damage, and the effects of a their auras make the Chosen a hard foe to bring down. However, if ranged DPS classes get a headstart, Chosen will quickly end up dead. However with a good healer backing you up, you will be unstoppable.

Path of Dread
The Path of Dread is highly offensive, focusing on direct offensive power while sacrificing some defensive protections. A master of Dread will be likely to favor a Great Weapon over a shield. They will be easily capable of picking up a shield when the situation calls for it... but they won't be happy about it.

Path of Corruption
The Path of Corruption is a cunning mastery for those who prefer to wait for their enemies to fruitlessly unleash their most powerful attacks before responding with deliberate and vicious counter attacks. A specialist in Corruption can outlast most enemies, letting their foes exhaust their attacks against their shield, and they will be the person who defines where the lines of battle will be drawn, since they -are- the front lines.

Path of Discord
The Path of Discord is one that delves more deeply into Tzeentch's arcane gifts, and masters of Discord have a limited understanding of how to manipulate the Chaos forces that swirl within them. They can unleash blasts of magical power, or twist the aethyr to unnaturally enhance their melee attacks. Their understanding of the nature of magic is still relatively shallow, however, and they can not hope to approach the skill or power of a true Magus, but even their brief flashes of otherworldly energy are enough to empower them as potent melee combatants.
