I have seen this topic many times and can answer with an ok answer. When Forge Of Gods will come out VoG will be like doing Vanguard Roc except longer. If VoG weapons were updated every update what would be the point of harder raids? You would have a overpowered weapon from doing an easy long strike. This is my opinion. EDIT: If they did it so you could upgrade it would have to be like 10 exotic shards or something hard.
