When level 60 is the level cap, none of the nerfs to level 50 content that you've presumably already cleared and farmed for months will affect you in any way. And I imagine SE's priority will be streamlining the process so that major bottlenecks are at 60 and not before.

No offense, but I'm really glad that none of you people have a say in this, because if I had a gil for every terrible idea or irrationally masochistic request I read on these forums, I'd have my mansion already. Stop obsessing about what other people are doing or not doing - you'll be 60, and there will be new unreasonably grindy or really difficult achievements for you to lord over the peasants.
