[Which mount do you like the best?]

I juse this all the time when exploring or travel the maps:Griffon and raptor are my favorite ones.Springer

Only use them if I really need them when exploring maps. Other than that I dont use them:SkimmerJackal

Have them but dont use them:Roller BeetleWarclawSkyscale

[IF you could kill off one of the NPC who would it be?]

The only characters that I like are Canach and Rytlock.Others from Dragon's Watch they can all die. Specially Braham.And as for some other characters that you interact throu story (core game and DLC) I don't see them to meny times as the ones from Dragon's Watch so I don't care.
