just wanted to make a suggetion dont know where to put it
i think they need to remove the limited job status from blue mage for a few reasons they use caster gear only from what ive seen so with mighty guard on they dont make good tanks even with the diamondback ability you cant solo the dungouns cause your too busy trying to survive not able to dps. removing limited job status would allow going into roullettes and getting dungouns opening up the chance to obtain abilities. along with that change the transition ability from massive heal but kill you to a rez of some sort maybe like rez member but drop you to 1hp and get debuff to where you cant use sacificing ability
if they think bluemage is too OP due to the white wind ability why dont they put a potency on it instead of your current hp also make a healer stance similar to the mighty guard tank stance but for healing and make it add abilities to some of the healing abilities like the AST this way they can add something like the angels snack from ff9 they just need to make sure not to make them better than a regular healer or tank
for the collecting abilities think it would be fun if they added some abilities like manupulate, lancet, mimic, and scan.
using scan to find abilities not being told where they are
Using mimic to use the ability that your target just used and increasing the chance of obtaining ability that you can learn
use manupulate into making mob attack other mobs for 12 to 20 seconds and cast benificial spells on your party
and lancet just like in ff10 to pull hp and mp to you and increase the chance to obtain abilities maybe make usable when mob is 10% hp left
