Those waygates were cool, I'd like to those pop up in a future patch (or maybe in the DLC?). They were a lot like a Skyrim equivalent of the propylon chambers in Morrowind. Maybe we could have some kind of system where we have to find the correct runes to able to travel to the right gate? I don't think it would make carriages obsolete, because we'd have to find the runes before we could use the waygates, and even then, the gates wouldn't (logically) be in the same locations as the carriages, out in the wilderness, high up on mountains or something.

Balls to fast travel, the more options to avoid using it, the better.

For them to fix the storage containers inventory so I can manage it better.

Spell making

For Bound Arrows to disappear off the ground.

yes! most annoying thing. I doubt they will ever fix it but i still have hope.

I would expect it to come some time around Dawnguard. Most likely before as some of the animmations etc in Dawnguard are in the 1.6 patch.

Better damage/magicka cost/perks/enchantments for destruction, and a fix for the absorb summon bug

Ever since I got my wish of a Horker mount granted, I haven't really thought about anything else to ask for. Life is good.
Maybe an option to help out those that are on the brink of society? Dunmer refugees, Argonian dockworkers, Khajit traders.
