So two things pop out. The first is definitely the overall shared sentiments of it being effectively Red Mage with a different coat of paint. It'd be like taking a White Mage, renaming various skills and then calling it "Geomancer". Another one is definitely the whole thing about using a scythe not just because of the name argument, but because scythes the usual vision as combat weapons simply never existed and never had adequate combat styles to them (war scythe doesn't count either since that's basically a glaive).

The other thing is that although it's nice to see maybe some effort taken into simplicity, it needs to be vastly more so. Again, if you want to make a better tank, please go level a tank for that better understanding of what's needed.
