Nostalrius Begins - Quality wow vanilla realm (1.12)

All I can find are lists of collected working addons with so much shit I will never need (interace reworks like that lock one, who uses such crap?)

What I want to ask is which addons do I REALLY need for vanilla? (vanity like better map, mob hp, enemy casting bar)
PvP is my main interest but there is also that must have PvE ones so I suppose...
appreciated if someone wants to name some.

Would recommend

Bongos hotbars for nice easy to modify hotbars

CCWatch timer for watching dot timers and CC, important in pvp.

Maybe some unitframes like X-perl unitframes

The only 3 I use, been thinking about a gather mod of some sort but ehh I'm lazy

I like Atlas, CEnemyCastBar, EquipCompare, MobHealth, SellValue. I also use DamageMeters but its not great, not sure if there is a better damage meter though.

Trying to find an addon for party member health and mana values.
