If you're looking for a rating, I'll give it a 4/10. Some things are done exceedingly well, but others miss critical points that place the character at a significant disadvantage.
For level 65, you did a very good job with gear selection other than the bracers. But the only, I repeat, only reason you ever stack stam above level 59 is to tank in Alterac Valley. Otherwise, you stack resilience. Especially at 65, where you can take better advantage of stat scaling than at 69. That said, the gear is so much better at 69 that unless you show me some numbers at 65, I don't think avoiding 69 makes sense.
So overall, good gear choices for a 65. But 69s can stack more stam and other stats (making them better AV tanks), and resilience outclasses stamina for PvP at this level. It's fun to see what access to 450 professions can add to 65, but the overall result still doesn't reach what a 69 can do.
