Inferno tactics.

Indeed, Inferno is the only faction where there aren't any outstanding heroes. All Inferno heroes invariably have some useless skill, even when considering map-specific builds. Besides the efreet specialist, there doesn't seem to be anyone else worth playing as... In general, it's better to play Inferno using a hero from another faction, and when choosing a hero, select Octavia for gold farming; she's also a good secondary hero.
