My point is still valid, the 10-25% comes when people are above the required minumum required iLevel, and it is still very much on point that anything exciting and able to get good stuff from, definitely is not based on the general population at all, I am not really sure on what you are trying to stick up or to defend.
SE has been put a stick into the wheel for decent progression in South Horn for upgrading armor for an instance, and there already is posts and threads about, not just on this forum, but in the rest out the community not based on SE's FFXIV forums about that casuals should just gtfo and more when speaking of eg. Forked Tower, that should had been like the content people could just get engaged in and more to it, though maybe the tougher situation or longer, if not getting it all done by the book as it is.
Bozja and Zadnor left room for that, where the better players in the start and at anytime could take charge and those lesser fortunate could ride it off while still doing and difference and learning from it as well to pick up roles and to take on actions in future runs of Castrum and Dalriada and likewise Delubrum Reginae, you can always add a savage mode to it later or requireing quite a bit more of action, as long as you DO NOT hinder progress for either pool of players.
