The first of the two new tombstones will essentially be "Darklight 2: Electric Boogaloo". The baseline gear expected if you want to competitive in the new raid. The second can be expected to be just like your soldiery or poetics.

Now the real change is the normal vs hard mode of Alexander itself. Which can be seen as the normal or heroic versions if we're going to recycle terminology from other MMOs. I can see normal mode dropping gear, and the hard mode dropping slightly better gear, probably with the same look. To keep raiding healthy you always need to have that good carrot on the stick to encourage players to waste hours of their lives dying to the same fight over and over

So yes, I do think Alexander Hard should drop "the best" gear available, as a immediately visible reward for the player's hard work and dedication to learning the fights. Even if its as much of a "Wow its nothing" stat increase like the whooping 5 extra ilvls on Coil Weapons.
