Higher-ilvl weapons would also serve as glamour, you know. And there'd be nothing stopping SE from adding other vanity things, just like they do now. I'm taking it as assumed/obvious that some vanity will be included in whatever the rewards are. Why wouldn't it be?

Think of it this way - if there were five fights a tier, with the +5 ilvl weapon and a mount coming at the end as usual, would anyone complain? No, not at all. Even if the last fight were on another difficulty level compared to the rest (see: A8S).

All I'm saying is that SE should use a similar incentive set to what they do for the hardest fights now; the one that's always been successful at getting people interested in tackling such hard content. I don't see how this is crazy in any way.
