Using new players/poor players as an excuse for game change is not that persuading, especially for an item that is still avialable from NPC. Sure, that shield does not have FC1. But Getting extra FC1-2 on the suit is not that hard. Keep in mind, even when HCI is spawning, getting a HCI 15, DCI 15, and FC1 is much much harder than today's Order Shield+FC2 from the suit/weapon. If the HCI is restored on the shield, then shields better than the museum colleciton (FC1 instead of FC-1, mroe resist, lower requirement) can be crafted by a bronze runic hammer.
So what you guys are asking is to greatly devalue the the museum collection and legacy items (old HCI shields) that have been around for a long time and still avialable for reasonable prices.
Talking about inbalancing, I would think those infamous sandles and sashes are worse offenders.
