Being hated for playing 69 is actualy the funniest part.
How to find the best gear:
wowhead.com>Database>Armor>*armor type*>*piece of gear*
Filters:
Req level x - 69
Additional filters...>Equippable items>Has gem sockets
Sort by Req
Ignore Heroic pieces (obtainable 70+)
More sockets are mostly better, but you better compare stats.
If you use intel/crit or agi/crit gems, I recommend going for gear without crit, so you can get secondaries more balanced, but this also depends on your playstyle.
Idk about weapons, but you should avoid using staffs, coz MH+OH can get better stat with right enchants.
You can get trinkets from alchemy, engineering, classic raids or Mindtap Talisman is nice. This also depends on your playstyle.
You can check my priest in signature. I am missing feet and 3 enchants to BiS.
