No, there aren't any calculations in these operations so there wouldn't be a noticeable load on the server. It also only has to run this operation once per every guild hall instance load. Maybe a fraction of a second longer guild hall load times. Databases are optimized for CRUD (create, read, update and delete) operations so this simple fetch is a drop in the bucket.
Considering that a guild hall is its own instanced zone, it should be negligible. I am for more immersiveness, so it would be nice to have: 1. Guild Banker (anything) 2. Guild Librarian (scrolls, spells, tomes, book, note) 3. Guild Apothecary (potion, poison, bandage) 4. Guild Bartender (food, drink, alcohol, wine, beer, ale, stout) 5. Guild Armorer (armor, weapon) 6. Guild Trader (tradeskill items) Even so, just a librarian and a trader would be nice.
Guild Bank - Anything Guild Consumable Master - Potions, Poisons, Food, Drink, Powersources Guild Collections Master - Collectibles items Guild Tradeskill Master - Tradeskill items Guild Spell Master - Spell Scrolls and Melee Tomes I think that breakdown makes more sense. Having the apothecary and Bartender seems redundant, and not having a collectible Banker seems like an oversight since those are a big number of house stored items Id guess.
It is not very immersive. How many times do you and your buddies hit the "consumable master" for a beer and pizza? 7. Guild Archivist (collectables) I'd stick that one in the library with the librarian.
It could not be that difficult to allow two banker types for a guild hall, programming wise. Let's do it.
These would be nice, i think the limiting factor is the sheer number of items that the database would have to store/load for the instance. They do have memory restrictions and pushing the limits effects lag and zoning times.
They should also add in the tribute window a TS tab, I have most of my trophies maxed and have them placed in house, having a separate TS tab I can just put them all there and not have to swap out all my 8 stat trophies when I want to work on TS, just simply Activate the TS tab when needed and be able to enable 8 trophies at once.
