Legendary armor rune memory
That, or even better a new system could be “feeding” runes to the various pieces of legendary, this way any time you change stat you can select the appropriate rune from a list of any rune that has been on that armor piece. This could keep the prices of runes from falling too much.
The same system could be implemented for weapons too. Seeing the recent articles in which they aim at making the “legendary path” more complex than “farm x gold, you’re done” it would also make sense to improve legendaries a bit.
stated a similar theme some days ago but well.. no one seems to really care..

The biggest problem imo is that, even if runes were dirt cheap, it’s still significantly less convenient to have to apply new runes to each armor piece any time you switch builds. Why spend so much on legendary anything when plain ascended is more convenient?
Also, in case anyone is wondering, this is in raids instead of HoT because legendary armor is primarily a feature of raids, not general HoT content.
I doubt they’ll address this since legendary weapons have always been in a similar boat with sigils (for example sword on a ranger could be used for both power and condi builds.) Legendary armor will just be a skin unlock and no one will use it for the stat swapping.
I just want to say that this is already on ANet’s radar. I’ve made sure they’re aware of the current limitations that stat-swapping has on legendary gear through my reports.
