Been working on leveling GEO, and with looking at its gear and spells on top of the playing experience, I have to wonder where it is going to end up.
Its buffs, debuffs and nuke-ra spells push it to the front lines to get the most from them, but with being limited to mage gear staying up close will be problematic at best against enemies with aoe or hate reset attacks. GEO does get the WHM hammers and a B? club rating which would of made melee more of an option, if it had the gear to support it.
With the mage gear and elemental spells would think could stand back and nuke, but with only getting up to tier 4 nukes, and no native Magic Attack Bonus traits, the nuking option does not look promising. I remember seeing something detailing out the different effects of Cardinal Chant, but been unable to re-find it, and recall one direction being MAB. From having leveled SCH, I know how important those MAB traits are to nuking, so unless Cardinal Chant provides plenty of MAB when facing the right way, nuking may go by the wayside unless the nuke-ra spells are fairly potent as well, but that places back up front as a squishy mage.
So then it gets into the realm of playing like Bard. Which due to the radius of its buffs and the limit of one indi and one geo spell leads to problems as well. Have to choose between mob debuffs, front line buffs, or back line buffs and with only two being able to be up means have to choose carefully. Have no problem with that until look at Bard, and the good ones keep up two debuffs on the mob, two front line buffs, and two backline buffs, and does not need to stay close to the mob for its debuffs and front line buffs.
GEO's abilities push it to the front lines, but its gear and squishy-ness push it to the back lines. Does it have the tools naturally to be able to be an effective nuker? If it doesn't have the tools to effectively nuke, will it get gear options to make melee range more feasible? As currently its place is going to be decided more by Cardinal Chant's effects and potencey, and how useful the nuke-ra spells will be. Otherwise its going to be likely relegated to subbing WHM or RDM to help heal and haste groups.
So where will GEO end up? There is lots of promise to the job, but it seems to be pushed in a few directions while not appearing to have the tools needed to go in those directions.
