We’ve got ascended armor, weapon, trinkets, back piece, amulet, rings, infusions and now even food.
Everything we can equip in our gear slots has an ascended version with better stats/effects.
Runes and sigils went from exotic to legendary without any better stats/effects and is missing that Ascended version.
If we were given that ascended version with better stats/effects, perhaps it would make the cost of the legendary runes & sigils more justified.
