Like many, I was pretty surprised the devs ignored Crystal tower as part of the relic chain. The queue times are ridiculous, and something like relics would keep it alive for people that have never run it, or are after glamor/minions.

Another idea would be achievements for completing sets of armor drops, sort of like the temple/pirate/mumer set achievements, or raising the tome rewards significantly.

Or you know... add a raid roulette.

Anyone else have ideas?
