Idea: Party activation abilities

[KorPoni]

That'd be awesome to see a party activation ability for each job. These abilities, when used, give all other players in your party the chance to activate the same ability, or add their own ability to the pool. Either way, recast would be shared no matter what ability you use.

Also, the effectiveness of these abilities are dependent on your party size. The more people you have in your party, the more effective the abilities become. The bonus can increase or decrease as people join and leave your party, and only works for party members within range of you (like Sphere).

Example:

Warrior
King of the Hill - Gain an attack and critical hit chance bonus, and give all other party members the chance to use King of the Hill. (You can't give someone who has King of the Hill a King of the Hill chance.)
Level: 99, Recast: 30 mins. (For all Party abilities) Duration: 5 mins. (King of the Hill becomes usable to your party during duration.)
*note: Attack +2, Critical Hit rate +1% if solo. Then for every party member, you gain an additional +2 Attack, +1% Critical Hit rate.

Black Mage
Black Hole - Gain a magic attack bonus and magic accuracy bonus, and give all other party members the chance to use Black Hole. (You can't give someone who has Black Hole a Black Hole chance.)
Level: 99, Recast: 30 mins. (For all Party abilities) Duration: 5 mins. (Black Hole becomes usable to your party during duration.)
*note: Magic Attack +1, Magic Accuracy +1 if solo. Then, for every party member, you gain an additional +1 Magic Attack, +1 Magic Accuracy.

Puppetmaster
Class Act - Gain an attack speed bonus, and your pet gains an attack speed bonus, and give all other party members a chance to use Class Act. (You can't give someone who has Class Act a Class Act chance.)
Level: 99, Recast: 30 mins. (For all Party abilities) Duration: 5 mins. (Class Act becomes usable to your party during duration.)
*note: Haste+1%, Pet: Haste+1% if solo. Then, for every party member, you gain an additional Haste+1%, Pet: Haste+1%.

Edit:
All of the names should resemble something ultimate about the job's themes, such as WAR's ultimate display of dominance "King of the Hilll" or PUP's best entertainment display "Class Act". Here's my ideas for names for the abilities:
WAR - King of the Hill
MNK - Physical Ascension
WHM - Overflow of Life
BLM - Black Hole
RDM - Crimson Atonement
THF - Gran Theft
PLD - Impenetrable Fortress
DRK - Gates of Chaos
RNG - Call of Gaia
BRD - Concert of Champions
BST - Abandon Civility
SMN - Spill Soul
DRG - Dragon Form
SAM - Soul of the Blade
NIN - Shadow Form
BLU - Unleash the Beasts Within
COR - Sail the Seas
PUP - Class Act
DNC - Performance of a Lifetime
SCH - The Best Strategy (Translated in German, which I don't know.)
