I don't typically post on these forums and I won't be responding to players who respond to this post because it isn't aimed at you!
For the devs:
I'm excited to see what the new system brings and I do support giving you all some more breathing room in the rune/relic design space, but as someone who grinded out 7/7 legendary runes I want to let you know that the uncertainty around how much progress and what will be required from a 7/7 starting point just feels terrible. As with most of the legendary systems I know there will be some kind of time-gating around the materials used in relics and given that it will be 6 or more months before we're even able to get access to creating the legendary relics, whatever timegating associated with getting back the functionality we're losing, is going to be anxiety driving. I only speak for myself here, but I invested my time and effort into legendary runes because I wanted the flexibility to tinker and the opportunity cost for investing that time into other parts of the game is real. Unlike legendary weapons or armor which have a "show off" component, the legendary runes are really there for the quiet nerds who value gw2 as a sandbox experience to play around in.
Please consider grandfathering the existing 7/7 crew into having a legendary relic once it's available. It's already such a heavy investment in time and resources and it would be a great way to let your players know that you value the time and effort we invest into the game. If that's not an option then at the very least give us a heads up on the time gated materials required to get us the relic so that we can plan around that early and hit the ground running to get back the functionality we're losing.
