Except it isn't just as hard as it was before. It's significantly easier, what with 10 more levels, and some awesome gear.
Difference between level ups and addressing one particular piece of content now isn't there?
It would be ridiculous to make every previous event harder just because of level cap, especially when they are rewarding gear for lvl 75 players.
And if it wasn't obvious from my agreeing with the OP, I didn't mean hard as in killing Byakko is just as tough as before, I mean hard as in difficult, a pain in the ass to keep players around as your ls is waiting on one NM to spawn just to complete a pop, or spending a couple hours farming diorite while if lucky getting 1 or 2.
