Ignore CP requirements for zones.

 

What is the BEST location to farm EXP per hour?

 

It's between:

1) Nightmare

2) Cron Underground

3) Hasrah Ancient Ruins

The highest cp where you dont use any potions.

Hasrah ruins, or cron castle underground are the best if you use the soups and the bagels if you have any left. The soups and bagels increase FIELD combat xp, so they do not apply to nightmare.
