I went at 62 with all my grps. AV 61-70 you earn full honor at 70 lvl BG. I always work 4-5 in a weekend then back to lvling . for AV weekends i live in it. 5 hunter grp was most fun. 3 mages 1 holy piest and prot din was also fun (aoe tower anyone)

do not listen to talk you must be 70. If you are instance geared you will have a good shot of taking down 70s. I do av to get 75k honor for turn in at 70 to be able to run wsg , ab , eye at 70. works for me
