On Remix there are roughly a couple hundred weapons shared appearances that are available to learn. I believe it is close to 600+ sourceIDs for all the weapons that drop from all the different difficulties.
-Each of the outdoor zones in Pandaria
-scenarios
-dungeons
-every LFR wing collective groan
-normal raid
-heroic raid
-mythic raid
I may be forgetting one.
With so many of these appearances potentially only being available within the Remix event. Many players are concerned about time restraints to collect these items.
Part of the dilemma for many is how inconsistent weapon drops are.
Outdoor zones drops have a 1/5 drop chance versus the armor components when you are mass murdering mob nodes.
LFR weapons cant be traded with other players. Causing some to spend 100s of LFR to get their weapons. (All weapons).
Many people use an addon to identify other players in normal, heroic, and mythic that have weapons that drop they can use after each boss kill. Having that addon auto reply asking for the item in whispers.
The super short version of this in most peoples mind.
Arsenals?
The means to bronze up the vendor and walk away with weapons seems practical at this point in the event.
We all have the reasons, desires, expectations built up in our heads. Patiently awaiting the addition of Arsenals every downtime. Every maintanence. Every packet delay that causes a second of lag.
Thanks for listening.
