The relic is not a raid weapon. It may be good enough to raid, and upgraded it can be better than other non-drop weapons, but it is not a raid weapon. After zenith, the relic had been about non-raiding content. Yes you can get the relic quicker if you do harder content, but it isn't required. Hence it would be contrary to the positioning of the relic to tie it to the Trials again.
If you are looking for a raid weapon, there are plenty of drops at the various item levels.
The later stages of the relic are not tied to the Trials for a reason. There are people who don't do raid and trials. They would love to have a nice relic, too, and the current relic is exactly the ultimate weapon for them.
Yes they don't need it, but that isn't justification for taking it away. Saying that if you don't raid you don't need the relic so you shouldn't be able to get it, is like saying someone has only 1 child so he doesn't need all that money so he should be prohibited to become a millionaire.
IMO the relic is perfectly fine as it is. It is a grind weapon. It is something you do now and then over the course of a patch, then the next patch, and have something tangible that is a representation of the combined efforts over a long year.
