Will this achievement still be available when the echo buff becomes available in 2.2? Not a huge deal or anything, I just think it would be cool for SE to lock it out in order to show the players that downed Twin pre nerf. You could argue that players could do it without the buff, but then they could farm all the higher gear coming in 2.2 and go in with full ilvl 100/110/120 (w/e it raises to), which would give an advantage to those attempting it after 2.2 that we don't have at this point in time.

Again, let me stress, not a big deal, just curious I guess. I see people upset about their gear becoming obsolete, which is something I really could care less about, but I think our hard work and skill should be preserved at least in an achievement form.
