If a player has reached the point where they are ready for EX Trials, they should be looking up guides on their own, making clear parties in the DF, etc.
While some people like the challenge of old synced content, and minimum ilvl content, there are far more who do not.
And if we're all being honest, EX content has zero bearing on the main story. It's completely optional content.
