There needed to be a good mixture of easy and difficult dungeons/trials to suit everyone. Some players like a challenge (Lev X and Coil), some prefer the grind (HM dungeons for tome cap every week), and some are casuals (who occasionally might do a mix of dungeons or primals and not fuss if they don't cap tomes or get drops). You won't see the casuals hitting the harder content like the static group FC's are (especially Lev X and Coil especialy since they aren't easily accessibly via Duty Finder yet). People who focus on working for the Coil drops, Lev X weapons, and rare mounts earn it. Casuals should not have access to these items unless they change their play style, gear up, and earn it.
