Oh, I'll like those things, a break from the constant "Kill all these things!" Which reminds me of WoW's Winterspring, "We are trying to save all these animals! So kill 40 of them!"
Maybe some radiant NPCs showing up as new members,all with different skills, which as a leader, you will decide in what area they should train. You could also send groups to places. The leader of any guild could also chose how much gold to spend on each area of the guild! Should they spend money on weapon and armor repairs? Not spending much gold in repairs can cause members to die during missions.
How much gold to give to their members (Lower amounts cause people to leave). I think I'm rambling, in a nutshell, I do want something other than "Kill this!"
I think the radiant quest are a step in the right direction, while generic they give you something to do.
I do love the "human" element in games, I personally loved the marriage and adoption in Skyrim, while simple, it added, as silly as it sounds, something special into my roleplays. My married characters now had a more stronger reason to survive and come back home. My more general labor type of characters now had a reason to work and earn money instead of the "I need enough to buy food and something to drink." They will save up to buy their kids toys and what not. It's silly I know ^^.
