i love rift. played in all the beta's and currently playing head start. there is so much to do in this game! rogues can tank, mages heal, rangers can be support. there is no end to the great things in this game.
Rifts: events in random areas. mobs appear and you defeat waves of diffrent monsters, the amount of help you give the better the rewards.
Invasions: huge events, huge waves of elite monsters send forces towards citys or outpost and try to take over post. team up to prevent. if succesfull get rewards just like rifts. if you fail, outpost will become unusable untill a force defeats the mobs.
The list goes on and on
