All the bosses in Aglaia, and even sometimes in Euphrosyne as well, go down too quickly -- but yeah, it's especially noticeable when you miss out on the "balance" phase of Nald'Thal. It's sad to think about first-timers not getting to see it. Heck, our items levels are going to go up a couple more times by the end of the expansion, so there may be a time when we simply don't see that mechanic ever again. New players won't have any idea what they're missing.
