I think the nature of people who play this game is extremely revealed on these events (and please, don't get me wrong, I'm not saying it's a bad thing, it's just the way it is). When someone finds a strat for anything (pvp team, event bosses, pve, farming, etc) that is in some way profitable, the rest will follow.
So, I think your complaint is more related with the nature of the community (of people in general) that with the devs, the boss or the game.
Some reluctant player could implement his/her own strats, find new ways to beat the boss. But, a new iteration of the loop will come, people will follow and clone the strategy. Is easier to do what you did, watch and learn. It will result in no losses and (the best part for the most) they don't have to think how to do it by themselves.
Humble opinion...
