Ill start with Cryodiil:
I wish cities in Cryodiil look like Morkarth, Whiterun, Winterhold, Solitude in Skyrim what can be taken over by guilds. Inside that city, guild members can create houses (what will cost greatly) maybe even stack them to a maximum height if there is no space. I also wish that guilds can create smiths, general shops in there city that are all owned by players of the guild to sell there items to there own guild members or allied people of that faction who visit the city.
Armor:
I hope for customizable armor and weapons for example a RedGaurd ''suit'' where you can add ebony should plates and maybe mix RedGaurd boots with steal ones. I also hope for color customization in limitations.
What are your suggestions or ideas?
