I played during season 3, when the Efrideet's Iron Cloak was obtainable, yet I can not use it in fashion because my collection tab does not recognize that I obtained it, due to not having one when the game started tracking for the creation of the collections tab. Despite this, I due have the ornament available for the cloak during that season from Iron Banner, showcasing my participation in IB during that season. I feel these armor sets from the dark ages should either be made re-obtainable, or be made available for synthesis for those players who can use these ornaments, as they obviously show participation in those activities during those time periods. Examples like this where I have the cloak ornament, but the actual cloak is listed as un-collected should force those items in collections to be made available for armor synthesis, due to them being required in the first place.
