Great thread here. I am glad Ms. Paiz has moved on and we are under the auspices of Rowan.
My wish list:
Scale all the instances & raids. My kin's playstyle is slow static leveling with Stones of the Tortoise equipped at most times. We love replaying the instances at different levels. This is doubly true now that the skill trees have changed the game's battle mechanics. I would love to see scaled versions of the Moria instances and others that consistently drop barter tokens (enough with the RNG) to everyone who participates, for incomparable level-scaled gear that is thematically & cosmetically appropriate to each dungeon.
Implement crafting directly from vault inventory for VIPs. I have a full set of max'd Guild crafters and as a VIP I'd love to be able to craft recipes using ingredients that are still stored in the vault, rather than pulling them into my personal inventory. This would be a huge quality of live upgrade for VIPs.
Provide more incentives for grouping: a full 20 - 95 leveling path through scaled instances only with bonus marks & medallions, for example. Provide a venue for those who prefer to group and take on challenges that way. Your players will come back if there are fun, engaging group dungeons to run with barter token non-RNG rewards, interesting and unique set bonuses, and lovely matching cosmetics.
I'm here for the duration, b/c I'm one of those who loves landscape, instances & raids too, but I'd wager some clear communication about new group content would bring back some lapsed raiders and instance runners. These are people who are sad to leave the game, they really want to stay & play but feel there's nothing for them now.
