Now that we have flying I feel that it's only a matter of time before players will finally discover a hidden Raid on an uncharted island only reachable by flying mounts. This island would be inhabited by Lv60 Cactaurs and should take a player anywhere between 3~4 days of flying to reach it (Because it's so secretive and hidden away from the general public).
On that island we would discover a colossal Cactaur with a giant mustache who happens to be the Cactaur Primal threat looming on the uncharted island where Minfillia is held prisoner and you as the Warrior of the Light has to free her from her cactus binds before she is riddled with 9999999 needles.
Ideally this would be a timed Raid dungeon where if you cannot clear the whole thing within the first 55 minutes, the hostage will be killed off and it'll be gameover for that raid group during that week's raid lockout. Because unlike Warriors of Light, Minfillia's respawn timer works differently and she can only respawn once a week.
I guess for rewards it can be a new tier weapon which could be highly sought after because it will be designed with a cactaur theme, kinda like mooglemog's drops.
Warrior: a green spiky axe adorned with a mustache
Paladin: A longsword forged by a cactaur, it's green with arms and legs which resembles a cactaur
Monk: Pair of fists that seems to have been crafted by fixing severed head of a cactaur onto broken pair of katar
Dragoon: Spear created from the very mustache of Jumbo cactaur himself, as you wave it around it has a tendency to add mustache debuff on the victims. Mustache debuff is not available during pvp
Bard: A live Cactaur strapped to a stick. Shoot Arrow animation is replaced with an animation of your bard holding out the Cactaur stick which prompts the Cactaur on the stick to fire a needle from his face as a arrow.
White Mage: No idea
Black Mage: Each time you cast a fire spell you gain a debuff that slowly turns you into a Cactaur
Summoner: You gain the ability to summon a Cactaur minion that will fight for you for 3minutes. Omegataur is about as large as an average Goobbue if not bigger by a head.
Scholar: Your arms turn into a cactus
Ninja: Melee strikes have a 5% chance of proccing 1000 Needles. This chance doubles if the enemy is on 10% hp
Dark Knight: Cactalibaur, a majesty sword said to have been wielded by the first Cactaurian Emperor. It's been wedged into a stone and given to the Dark Knight as it is. A sword with a massive slab of stone still connected to the blade.
Astrologian: No idea, glowing ball of Cactaur head. It shoots needles at caster's face when healing spells are cast which harms the caster but increases the healing done by 10%
Machinist: Cacta-zooka. A missile launcher that launches a cactaur at the target.
