[Squirrelloid]

P3D: One of Army of Lead or Gold is E5, as is Petrify, as is Weapons of Sharpness. Not everyone has easy access to crystal shields, and gems are going to be rare enough as it is. And *excess* earth to keep fatigue down to sane levels might be necessary (I'd have to actually look at the specific spells again to confirm).

Considering these are also spells which can let armies compete in the endgame, and people are already complaining about lack of gemgens = fewer SCs, this could go a long way to filling the power void for those nations who can't straight up compete with nationals.

Also, virtually every other path is easier to boost, and by more, than earth is. And then it is in the running for highest average path level of its combat spells... not a well-balanced combination.
