It's hard to describe how frustrated I am at the explanation for Black Mage's changes.
"Future battle design may cause difficulty with casting spells, so we have shortened the cast time for a variety of actions."I feel like this should be self-explanatory, but the players who kept playing BLM instead of switching to another job liked this. They liked the additional difficulty of casting spells, and they liked trying to manage Astral Fire in the midst of battle mechanics. It provided them with a challenge that they found engaging. BLM players voluntarily chose to play a job that was more demanding and more punishing than others, because that experience was satisfying to them."Furthermore, the effect expiration of Astral Fire and Umbral Ice has been largely detrimental to attack power in situations where players must interrupt casting to address battle mechanics."
But you're so focused on "attack power" that you've lost sight of the fact that players play games because the moment-to-moment experience of playing makes them feel something. The damage output is just a contrivance, a carrot that players chase to give them an extrinsic motivation to engage with the fundamental game loop that is the actual source of their enjoyment. As game designers, I feel like you should know that.
And yet, instead of balancing these new mechanics around the game's existing jobs, you elected to remove multiple core aspects of BLM's game loop in a way that impacts the entire game for BLM players.
FF14 developers, for a decade you have managed to successfully design battle content that BLM players were enjoying.
What made you give up now?
I cannot understate the extent to which removing these aspects from BLM removes something valuable from the entire game. Whenever any player — BLM mains in particular — wanted to add a bit more engagement to a combat encounter, BLM was there to provide that additional layer of engagement. In that way, BLM allowed a wider variety of players to readily get access to a level of difficulty and engagement that was better suited to their needs. Now that option is gone, with nothing to replace it.
