Another week, another Patch 3.2 PTR build with no access to the new instances yet. I'm sure they'll appear on the PTR when they're ready (™). In the mean time, what tweaks and changes have they made in build 10072?
Well, for one thing, they added in the Crusader's Coliseum versions of the Undying achievements. A Tribute to Immortality requires you to reach the end of the heroic-mode raid with 50 attempts remaining (possibly a placeholder quantity), and without any of the raid members dying during boss encounters. It doesn't say for sure, but I would guess this is calculated in the Ulduar style - if you down boss A without anyone dying one week, boss B the next, etc., you get the achievement.
In lieu of the now semi-traditional
Proto-Drake mount fancy title, those who complete this feat are granted a black or white Crusader's Warhorse (as pictured above-right).
