@Astra - totally agree with more open world - it would have been great to fly from your dragon tower to the fords, given that you could clearly see it out there. I noticed the plume of energy coming off the tower looked like the one protecting the city in FoV, so maybe it was also an impenetrable shield? That would be a possible explanation/excuse.

I think the issues of being referred to as a "slayer" was that you were incognito in certain areas of the fords - e.g. the slayer camp would attack you if you revealed the truth. I assumed that this was also the resaon for those permanent anti-dragon shields around the docks and the slayer camp - to prevent you from revealing your identity by transofrming in front of them. Also, the salyer has obvious visual clues (the silver eyes) whereas there's no obvious way to tell you're a dragon, so it's natural for strangers to assume you're a slayer. At least by the time you reach FoV everyone knows you're a dragon.

@Vivaxards - I didn't realise there was an actual combat advantage for higher levels, I thought it was just XP, but it makes sense now I think of it - there were plenty of monsters that couldn't hurt me faster than I could regenerate. So I guess Wisdom is more useful than I thought.
