This has been going on for years now. Certain spells and items are only available from BCNM, and KSNMs old content but I still find myself in the same situation I've found myself years ago. Either it's hard to get anyone to do certain BCNM/KSNMs unless they have a valid interest in them. It's now getting harder to get people to join in certain UNMs as well now. Usually LS members and others aren't all that interested in taking time to do a run in these older content situations... and once again it cause some players that are trying to get some things done in the older content to be sitting out for months and years due to the fact nobody else is that interested in it.
I've heard it a few times, "Well ask around...someone will join." And it just doesn't happen. Unless it's for a Kraken club, no other BCNMs will be touched.
The whole goal of trusts and uncapping areas was to allow more players ACCESS to accomplish things that they couldn't before in the past. At the moment players are only allowed to use trusts in SCNMs that have Rem's Chapters as rewards along with a difficulty setting. All the BCNMs, KSNMs, and older content for conquest battles still have their old limits. Some of them are required, for example I have been trying to get a particular abjuration piece for some vanity armor. In order to even have a chance at getting the piece I need, I have to defeat an uncapped KSNM solo which drops a force spawn item, that gives me the chance to POTENTIALLY receive ANOTHER force spawn item which gives me the CHANCE to MAYBE get the abjuration piece I'm after. It would be ok if it weren't for the strategy required to defeat the monster pretty much needs more than one person. This is where trust should be available once again.
It's consistently frustrating that I can use Trusts in Campaign battles, Abyssea, Adoulin Colonize(etc), and certain SKCNMs...
But I STILL can't use trusts in Conquest battles, BCNMs, Prime Avatar and SUMMONER lvl 20 cap battles, KSNMs, Besieged, etc. It's very difficult to get other players interested in joining unless it's the newest or most beneficial gameplay to them. Please make it so the level caps are eliminated for one, and that trusts are available for the other. Either way, having trusts available helps quite a bit and doesn't restrict players that are pretty much forced to play solo due to others lack of interest in older content.
