Builds should not be fixed by loot. They should be fixed by updates to the build
How many MMOs have new gear being sideways to old gear, rather than upgrades?
My guess would be: All of the MMOs that dont last long.
Especially since this is raid loot, which should be the ultimate prize in the game. Not loot which can be gathered (very slowly I will grant) by running 3 LN dungeons over and over and over and over and over.
