I have an idea. Blue Magic
Insead of opening up 90% of class abilities to all classes. We instead fill Sentinel's now unfilled niche of a generic subclass. With a class that is commonly requested but currently impossible to work in and still reasonably please the fans as a class: Blue Mage.
Simply put: All players (Disciplines of War and Magic) will have access to "Blue magic" which will take the form of skills that either need MP, HP or TP to cast (as well as the usually free buff skills), as well as traits for those skills. Players can get the skills for a variety of monsters or other sources and place them on the Cross-Class skill list.
The abilities themselves will have a variety of applications to fill multiple roles for different classes, but will either have a long cool-down, require more points to cast or deal a debuff to either the caster, the entire group or everyone with a radius around the caster
Arguments I'd expect against this idea:
- But I wanted it as a CLASS: I think Blue Mage is inherently imbalanced as a class in a MMO that is more like WoW then XI. The method of learning abilities and the resulting high skill counts means that people will either be gimped or will be OP depending on their devotion to the class, especially considering that it can fill all three roles.
- But that will be OP: There is potential for abuse, yes. But as is, Blue Magic is uncharted territory for XIV, SE would have to code in new abilities to mobs and bosses. Basically the onus will be on SE to make sure the skills are balanced and that the mechanic will be implemented without any kinks.
