Perhaps a small blade attatchment on gauntlets, thus allowing H2H to have enchated weapons.
Bows should definitely do more damage; i believe i read something like this already however.
Places that have been 'found' already should be customizably labled on the world map. For instance, instead of just having the name of the place, players should be able to select what they want the dungeon to be classified as from a list of choices. Say you found a mythic enemy lair. Label it 'Mythic' and 'good loot', or what have you. Players should then be able to see their labels by hovering over the icon on thier world map.
On the subject of dungeons, rather than have 200+ (!) generic dungeons, there should be a few really unique and characterized dungeons. 75-100 perhaps.
Gold should be less readily available. By level 30, I had 100,000+ gold at all times, which decreases incentive to go dungeon delving, which is a huge part of the game.
Also, the enchanting and spellmaking altars are rather limited. Heres what I mean;
Enchanting altars only allow the max charge in your newly enchanted weapon to be 1600 (Grand Soul Gem). The max charge for self-enchanted weapons, if you will, should be increased, perhaps to 5000, by adding more soul gems.
Spellmaking altars are also limited in that homeade spells cost a significant amount more magika than spells that are bought. The magika ratio should be even, with the homeade spells costing the same amount of magika as thier bought counterparts.
