I'm still slightly confused with the new system for legendaries. From what I read/heard, we will progressing through only one legendary weapon throughout the expansion and anyone can do it.
As of 5.1, how far can you go with the legendary? Can you obtain the +500 gem yet? If you can make the LFR weapon drops your legendary, [as well as normal/heroic] are there going to be different ilvl legendaries?
And will each weapons thats capable for the legendary upgrade get their models per upgrade?
And finally, how many people are likely to obtain the complete legendary set compared to past legendaries?
