There is a reason why there are no casts anymore and i personally think it´s good that way. It just doesn´t fit phys. range classes. Maybe 1 cast like Midare for the MCH, but not more.
Instead of going the "easy" way, SE should give those classes a soul if you really want them to compete with others in dps.
- Dancer for example could have limited range and different dances you´ve to remember and play by yourself like ninjutsu. Not just 123 or the same dance with different highlighted buttons. Such dance-moves could have different buffs like "added dot effect, more damage, max. range increase from 8 to 15m", whatever.... such stuff with an internal cooldown, so the player have to adjust with them to the mechanics, skill-problem solved. Of course it´s not that big deal if you get used to it, but it´s something you´ve to remember, you´ve to adjust with the range dance and it fits the class.
- MCH could work with positionals. Not himself, but the robot. Let the robot attack from behind for 5 hits will load his attacks. If it´s done, it´ll grant a 15s damage buff for him, if he attacks the boss from the side. (or other way round). Ofcourse the player needs to have a look at the buff and have to adjust the robot with "from the side, from behind" skills. The robot will stay for a minute and has 45s cooldown or something.
- Sounds pretty dumb, but BRD could actually collect instruments spawning in a 5m radius around him for 10s. If you´ve collected 3 in a special order, you can unleash an soundwave with X damage and one of your menuet/ballad, whatever will be activated. Not just "click the button and enjoy" as it is right now.
Just brainstorming, but anything is better than just cast times. Being "free" fits the jobs well, they just need a soul / something to take care about. But hey, it´s FF14... all cool or variable stuff is getting dumb´d down e.g. astro cards or has a highlighted rotation.
Ppl would just spam it if it´s too powerful or don´t use it when it´s not. And having some sort of PLD rotation or "just another button" is määäh...
For real, SE just needs to stop to make everything too simple. Give us TP, armor/magic penetration and other stuff back, so they can do much more with any class.
