unynced/overgeared raids are ruining the experience (for new players), especially on such raids as the 2nd + final coils of Bahamut and extreme primals..
even going in them synced with a level 60 character (+ echoes), makes them quit a lot easier than they were originally back then (even with echoes), but unsynced is imo really too much for first kills
sure, some will argue "but they can still chose synced if they want too, let them chose", but almost no new player will chose it anymore, if they have the chance, theyll just run thru it synced or not do them at all (they should imo even be part of the main story or at least Alex Savage only reachable, once those are completed too)
those are still the best raids and good practice,..part of the beauty of FFXIV, was building up your character while earning each it with good raids (and the euphoria of bringing down some of those hard bosses)
