As many said, i also think the relic system should fully compensate those who had a full set of legendary runes. I share the sentiment and the disappointment in having to re-craft/work on a feature and part of the game i had cleared previously. Many have voiced their opinions already, which i share, so i won't be going further into that
That said, I would like to bring the discussion to easy ideas Anet could implement in the meantime. Here are some :
Give players with legendary runes so much of those (or an unlimited) relic-choice boxes so that we feel like we still have the effects of legendary runes
Postpone the relic system until the legendary relic is implemented
Leave legendary runes in game with their 6th bonus as is or have an hybrid system while we wait for legendary relic
I would like to hear your ideas and realistic solutions, the less development required from Anet's side is probably the easier for them so i tried to keep it simple
Some of you guys had similar ideas, sorry for not crediting you
