After completing each of the eight dungeons on the Elite difficulty, it came to my attention that there is more to life than just blowing stuff up. Crazy, I know. So in the interest of preparing for Nightmare modes, I thought it would be wise to invest in a few utility builds. While there are barely a handful of situations in the Elites where utility is useful (but not necessarily required), I know from the Looking for Group channel that they are more or less required for safe passage through a Nightmare dungeon.
Utility in The Secret World is much the same as it is in every MMOG: stuns, purges, cleanses, and debuffs. Each of these abilities is usually narrowed into the scope of one or two different weapon choices. This means no single person can be the jack-of-all-trades, making group composition important. By building a few decks each with one or two specific utilities, you can ensure that you will be an asset to any group.
