It's true the crafting halls in house K and House C are irrelevant. The Cannith crafting Airship amenity killed the crafting halls but there is a way to make them relevant again. Consolidate crafting altars into one/two generalized areas. Cannith and Heroic Shroud can still be a ship amenity and Lshroud should stay as is in the raid itself and leave TF where it is too since that's thematic. However, there are all these other little altars and crafting benches all over. Cannith wilderness and sharn docks for alchemical and raid stuffs, Cauldrons of Sora Katra and Cadance in Lordsmarch plaza and the Hut beyond respectively. theres also the altars in the 12 enclave and the soul forge altar in Hall of Heroes.
So instead of players running all over Eberron just to craft stuff why cant the crafting hall be utilized better and everything that is Crafting be in the crafting? I mean lets be honest all the Gatekeepers were stashed in the HoH until the grove was created. So doing a redesign of the hall of heroes isnt going to be a huge undertaking. there was even a simplistic building made in saltmarsh for the trainers. Anyways, Im sure Lahar is feeling a bit cramped as of late and it would be nice for him to have his own little Niche in the newly redesigned crafting hall and not get rained on all the time. You'll just have to build his section with nonflammable materials.
Heck you could even get rid of the crafting halls and take all the above mentioned stuff and redesign the Hall of Heroes. Besides the soul forge, a few vendors and the reincarnation grove the HoH isnt getting much use because really how many of use go and look at the hardcore leader boards on a daily basis? Most of all that stuff is on the first level so why cant the second lower level be redesigned to accommodate the consolidation of crafting? Pfff might even cut down on Lag.
