A little bit of new buildings

We have specific building for diplomacy: Foreign Office, Thieves' Den, Spies' Hideout, etc.. We also have specific military buildings: Infantry Quarters, Spearmen's Billets, Spear-makers and others. These allows us to build cities that are different; some cities are military oriented some are diplomatically oriented. Why wouldn't we add some new structures to "Trade" and to "Magic" sections? I know that in near future developers will add new magic structures (because we have unfinished "blights" magic, no building to empower it and 2 more schools of magic to come with new empowering structures), but what about market? I think it would be a nice idea to have structures that will empower your caravan's speed or that will allow you to have more caravans (so by default we would have a little bit less of them). Also it would be a nice to build a "Caravanserai" (for which we have a research already) where we could train slower caravan which could be accompanied by an army or guard but which will have more carrying capacity. Apart from this I think that Illyriad is a great game and there is a lot of new stuff that will come . Sorry for my English, it's not my native language, Thanks.
