Crystal hollows commissions or Dwarven mines commissions?

[SteveQian]

I'm trying to get hotm 7 but I don't know where to go for the most hotm exp, sometimes in the crystal hollows, it takes like 10 minutes to complete the commission since the location is far away but dwarven mines only gives me 100 xp per commission excluding daily bonus compared to the 400 from crystal hollows, which one should I do to get hotm 7?
