What do you want from bethesda's expansion? I would like an arena with a fight to the death tournament with other events like jousting.
For now, since my highest level character is 20, my wish list is relatively short:
1) I want axes and daggers we can throw. Now 'OMG Overpowered' just an alternative to bows and missile spells.
2) A way to bash doors. My burly Orc doesn't like picking locks (I have a thief for that) but many places can't be opened without Lockpicking. I'd rather take an axe or mace and bash them open.
3) A way to craft arrows and lockpicks. Again, not over-powered ones, just something nice like a +5% or something. It would give me a use for all those iron arrows and metal ingots I don't want to use...
4) A new area would be nice but as I said I haven't even seen the whole world yet so I'm good with waiting on that.
