Geomancers have had several iterations within the series where what type of ability/spell they would produce depended on the physical terrain (tactics) or at least the immediate environment (others). However this is not exactly their defining "end-all" requirement, but the Geomancer's trait people are most familiar with fall into this category- thus people assume the job will clash with FFXIV's lore. In truth though, Geomancer has been flexible enough throughout the series that it can be molded into whatever the game's setting demands (or allows). I've noted in some Geomancer threads before, but both FFXI and Explorers have Geomancers setting ground fields (like Sacred Soil, Fire arrow, whatever) that can either buff or debuff; no "earth elements" required. Since the job is fairly open to whatever style suits the game, and it literally can go either the "geo," feng shui or divination routes that are associated with it, it really does come off as something the developers can mold into what will work for their game.
