Those boss mechanics at the end of that video are something unique and a fun challenge I look forward to. It'll be nice to have some new mechanics to learn and grind through.
One thing that really enticed me is how they were
REALLY going into detail on their development of raids during the panel. They wanted to make sure that there were no "trash mobs" (but would be smaller encounters that were active, fun, and rewarding). There were no fights or moments (down to every few seconds) where there is no lull for
ANY roll. Even when moving from one fight to the next, there are dangers to be had.
It's a
CONSTANT action event with tons of new combat and, of course, shinies.
Also, remember -
20 mans have Epic (purple) gear.
40 mans have Legendary (Orange) gear.
Certain bosses in 40 man have Artifact (Pink) gear.
And, dropped gear isn't necessarily it's highest form, but require quests / actions to be had to actually make them stronger.
AWESOME.
