Joint strike being a mass event for everyone logged in, and everyone ques up together its more like you have multi-able parties under one large map fighting the boss? or even designing one that can bring every single player in que into one place to fight a boss together, thats what i though joint strike was until i found out its really just being in a party fighting a boss, and not like a entire task force of players taking on one huge raid boss together like 
Joint strike raid was designed to prevent the lag from the old big field bosses where 50+ players could be gathered at a time, so that sounds a bit counterintuitive to the purpose of JSR.
yeah if you put 50 players in one map, hehe xd, enjoy being unable to cast anything. Could be fun, would be fun, can’t be played.
