No it doesn’t. Only ONE boss in that wing drops tier. This myth is ridiculous. No one lost their minds over the years of LFRs and felt forced to run LFR.
And if you really feel that much of a sense of urgency to try for that ONE tier piece, it’s ONE RUN for that week. ONE.
And then you’d still be right back in there the next one if you’re that obsessed.
So this “argument” is a bad one.
People pay the same amount of money we do to play this game. This isn’t a caste system. Wing one hurts no one.
