Quick travel should be based on map - it's horrible to sit there and walk through 4 maps to get to one place because it's in between two quick travel points. And for those that say "get the portal spell" - I'm a ranger and I don't have much skill in magic.
A slight change to the battle mechanics. It's hard to believe that with a Dexterity of 42, a bow weapons of 18 (which gives me something like 27 to hit and 25 max damage + 3 because of my bow and enchanted arrows), that 9 out 10 shots hits a Taurex BUT 5 out of those 9 hits cause NO damage. It makes it nearly impossible to kill one without dying half the time, or fleeing in circles trying to get far enough away to keep trying. I'm not saying "make it easy", but if I have to rest for two days every single time I kill just one of those things, I get bored quickly.
Perhaps an increase in how powerful magic spells can be at lower level spells with a high level character. Even a 15th level Mage simply doesn't have enough mana (this is with the 20+ amulet and 20+ ring), for a sustained battle with multiple opponents because Fire Dart at level 6 only causes about 20 damage at most but sucks up 12 points PER shot. Deep Freeze sucks up 18 at level 3, and causes more damage but drains you even faster. An increase of say, +2 damage per every 2 levels after level 4 would make a huge difference and make it easier at times when trying to fight a large group at once. There isn't a whole lot of strategy for battles short of "blast at them till they die"

Other than those ideas, I love the game and can't wait for #2.
