Best way to get xp with highish guardian rank

I’m around 200 guardian rank and it takes a lot of Xp to get tokens so what’s the best method in getting xp(offline or online) please list all your methods I like to cycle through because it gets boring lol

Slaughter domes were it but no one can solo them now annd playing online only prompts nerf tsunamis

Slaughters dome specially the badass dome ( I dont remember the name, but the one that spawns idiots with rocketlaunchers ).

I think Graveward offline on Mh3 with 242.000k Xp is still efficient
And alot of legendarys too

Offline M3 Graveward is the fastest way right now, if you are focused 100% on efficiency.
