Training spots?

I know it might be a little too early, but seeing as we already know what things do, what would make for good training spots as an Aran?

Keeping in mind these three things need to be there:

• Large mob groups
  
• Good HP/exp ratio
  
• Small maps, or maps that can be navigated easily
  

I have a list of maps in chronological order (by level range) so far. This isn't factoring in the fact that entire maps may be skipped due to Aran quests.

 Maps

The Job category only shows at which job an Aran COULD start training at in a specific map.
