It's kind of like WoW but a lot better in some ways, the rifts are similar to public quests in Warhammer Online where it's like a mini story and anyone can join in for the rewards and what-not. You eventually have 3 jobs, like I started out as a shaman, then I got justicar, and later I am going to get druid, so I will basically be 3 classes in one, then there is giant talent trees for each job and you can spend as many as you want in each tree. Again it is similar to WoW basically having 3 trees to spend points into, but this game encourages you to spend points in all 3 trees and also to build multiple jobs, so like there is 3 trees in WoW but you have to go full enhancement to be any decent, Rift encourages things like being half restoration and half enhancement. Also you can have 3 different setups, like dual spec but 3x, So I can be full shaman, full druid, and full justicar, or I can be 1/3rd of each, then the other spec half and half, and the other spec another half and half combo. So I can go anywhere from a hardcore group healer, to a full on melee self-healing machine, to a decent healer that also holds his own.
