The quest exp rewards are so much better now post 20 I just don't bother with anything that is a collection quest that does not have a reward I want or is part of a chain I need. Do yourself a favor don't be afraid to do every kill quest they are the opposite of collection quests for MB'ers as they have better returns for us, In your case three times the exp for three times easier work. then just move onto a new area and do all there kill quests then go to an instance if you feel you missed out on exp. Variety is the spice of life and all that. I only do escort quests on Pve serverrs, on pvp you are just asking for grief.

One kind of collection quest I do do, are instance ones, they keep the tedious nature of instances productive for a bit.
