Very nice toon, from MOP days it looks. Unfortunately I don’t think any of those blues or PVP pieces are BIS. However that is good for you, because now you can make the decision if you want to level him out of the bracket or gear up.
With gem slot availability fairly similar, I like to group 60, 70 and 80 together. 60, you will have a lot of fun and not be at a disadvantage to 69s.
70 this is the same thing, with 70s having a bit more advantage against 79s than 60s do against 69s only because their secondary’s tank when you get close to 79.
(Edit: not to be confused with 70s being stronger than 79s, just compared to how 60s are to 69s, they have a better fighting chance)
80 is a whole different story. A 89 twink is 2 xpacks ahead and there is a noticeable different. You might find yourself being killed by a random 89 BM leveling hunter. It’s just the nature of the bracketing system now. Blizz unintentionally, maybe intentionally closed the gap a little when the stat squish happened, and stats on 80 gear were closer to 89 than they were before. But the bracket just goesnt feel twinky at all unless your 89.
Where you go from here is up to you. You could stay 80 and I’d be able to provide tons of awesome suggestions on up to date gear because I think they are still cool twinks with the kind of secondaries you can achieve. But also if you want to level out, I can suggest bracket options of what I think rogue would be gimp in
