Guild Wars 2

Celestial armor, divinity runes, and traveler’s runes were all “don’t have a lot of certain stats, have some of all the stats”. Then new stats were added and this equipment was unchanged.

Was this an oversight or is it ANet’s intention for those equipment sets to no longer be “all stats” and instead be “some stats”?

It’s always been possible for them to put +x% boon/condi duration on amour/runes even before concentration and expertise. Since they never gave celestial boon or condi duration I’d say it’s intentional for them not to have it, with the oversight being that they didn’t change the “all stats” text on certain items to “power, precision, ferocity, condition damage, toughness, vitality and healing power”.

Right, it was always possible to put %duration, but it wasn’t a normalized (or realistically accessible aside from giver’s weapons for condis; giver’s armor and %duration upgrade items had too high opportunity cost to use for any competitive build) stat on gear before and it is now.
