4. Javik
Unless you bought the N7 collectors edition like I did, or purchased the DLC, the Prothean, Javik, will still not exist in your game and you will still miss out on classic Liara/Javik moments. That hopefully few extra hours of content that you will be receiving with The Extended Cut will still not delve in to Javik, who as much as Bioware try to deny, is an important element of the story. Hes a Prothean for effs sake! Could there have been any better reason to make gamers dish out cash for additional content? He represents three games of questions, mysteries and artifacts that blow your mind. Do any of you remember encountering that Prothean sphere in the first Mass Effect and then again in the sequel? I didnt mind eventually paying for Kasumi and Zaid in ME2 to complete the experience. They are both side characters whom you could do without, and the Batarian introduction in the Bring Down The Sky DLC in the first game is interesting yet not pivotal, but a Prothean? Were Bioware for real with the From Ashes DLC? Everyone would want a piece of that action! Having played through the game already and ready to do so again for The Extended Cut DLC, I dont believe anything the DLC will offer can be more important than a living Prothean who can answer your questions and argue with Liara over whats myth and what isnt.
