Druids and Planar Sickness

[Knight Of Pentacles]

Druids and their connection to natural things presents an opportunity for them to react differently to planar energies.  I think it would be neat if planar sickness progressed more quickly in outside, abstract planes (Think Abyss, Baator, Celestial, Mechanus) and more slowly in natural planes such as those of elemental and faeish aspect.  Additionally perhaps in certain areas of the Cities the rate of recovery is improved.
