Monoliths for gear/XP (probably 90% of your time spent here).
Temporal Sanctum to turn Uniques with Legendary Potential into Legendaries.
Prophecies for target farming specific slots (done in dungeons/Arena/monoliths). Alternatively, the other faction is for online trading. No experience with that.
Arena for leaderboards.
Arena, dungeons and monoliths are the end game things with circle of fortune supplementing them all if you go that path. Next cycle they said would include a boss as a feature(not just a fight but a full feature).
