Geomancer, Do you want it?

[Bita]

If you've watched the alpha videos its not like the terrain varies like in tactic games.

.

Basically it would depend on the zone you are in. Also weather patterns/atmosphere as secondary and tertiary mediums of grabbing an element or skill. So Geo could have "Use terrain" "Use Weather" and "Manipulate Atmospheres" as main skills/spells and perhaps have a few different traps that are set apart from using terrain.
