Here are some ideas that I had, hopefully some seem appealing and of interest to everyone, if you have suggestions to modify and of these, feel free to post with the correct section.
1: The option to terminate any Temp. Key Items that you may not ever use again(Would also end/reset the quest or mission it was for to prevent glitch of not being able to go back and do that event at a later date)?
2: Alternate names for Magian Weapons to enable macroing Weapons that share the same name, but have a different augment. Such as, perhaps... Example: Indra's Staff +2 with [Magic Accuracy+1, Magic Damage+5] augment would be called "Indra's Staff(MAB)+2" and an Indra's Staff +2 with...let's say [Avatar per. cost -6, "Blood Pact" delay -10] augment would be called "Indra's Staff(Ava)+2". I know players could just deposit one of the two Indra's Staff into Mog House or Mog Sachel, etc., but what of those with Weapons that modify a Pets attributes that share the same name? Such as the Guichard's Axe for Beastmaster.
3: Adjust the Ninja ability "Mijin Gakure" to have a Reraise effect in it.
4: Give players the effect of "Auto-Reraise" in Campaign Battles.
5: Allow the Blue Magic spells "Wild Carrot, Magic Fruit, and Plenilune Embrace" to be casted on Players/NPC outside of the Blue Mages Alliance.
6: Re-construct the Summoning Magic "Spirit Pacts" to use magic more efficiently, example: IceSpirit will cast "Frost" several times back to back on more than one occation rather than a 600~800 damage "Blizzard IV" or "Freeze". LightSpirit will cast "Regen", "Protect IV", "Shell IV", or "Haste" on a player rather than "Cure V" when they are even below 50% HP. I wouldn't see these adjustments as "Game Breaking" if they were applied. Perhaps add the new tiered spells to SpiritPacts, "Blizzard V", "Freeze II", "Cure VI", "Regen III" etc.. Also, rather than LightSpirit casting "Protect IV" or "Shell IV", allow them to cast "Protectra IV/Shellra IV" and/or "Protectra V/Shellra V"?
7: As a follow-up for "Idea 6", perhaps can add a second tier of SpiritPacts? Using the Abyssea Elementals image designs: "LightSpirit>AuroralSpirit, IceSpirit>HailSpirit, FireSpirit>BlazeSpirit, WaterSpirit>RainSpirit, ThunderSpirit>ShockSpirit, etc." Just some ideas for second tier SpiritPact names...if anyone has any better feel free to post.
8: Possibly add a new Astral Flow Specific Avatar? Bahamut maybe? Astral Flow>Mega Flare(?)Additional effect: Terrorize for xx time? Any thoughts?
9: Ballista in Xarcabard/Eastern Altepa Desert.
