71-80 aint bad, I mean cmon you have a group of 5 people to ward off any attackers. Of course, there will be the time when that lone bum calls in support and they camp you. Honestly though, I only had one day with that kind of trouble and once you pass a certain level threshold they seem to leave you alone. I noticed around 76 that not many 80s would try attacking me. When you can kill most of them in a few GCDs I guess they look for easier fish to fry =)

edit: as for the dailies, I dont think I have had any pvp action on any yet. This is mainly due to flyers and the fact that they are also working on dailies and just want to finish their dailies more than pvp.
