Yeah, the Legendary update sounds pretty cool. I have never had a character reach level 81, but I'd imagine doing so would be easier now with skills being able to be 'prestiged' (CoD-term I know)...
What has got me really excited about the update however (despite my little hope that there would be spears as soon as I saw the link on the main page, which is now obviously dashed
), was the fix for Esbern's potion - the The Dragon Infusion perk thing.
I had completely given up hope of it being fixed and moved on from it, but only so far as ***SPOILER ALERT***
trapping that dragon in Whiterun. ***END OF SPOILER ALERT***
So I hope the quest and bonus is salvagable.
