One of the largest problems with balancing FFXIV right now is the exclusions of classes/jobs in dungeons due to their lack of function to achieve speed runs.
Preventing class/job changing inside dungeons accomplishes several things including but not limited to the following:
- Prevents the exclusion of certain classes
- Increases the available balancing of classes/jobs
- Strengthens class/job identity
- Does not require everyone to level up each class/job to fill any spot
- Increases the accessibility of play for everyone (even those that have every class leveled)
- Creates more engaging and challenging content, rather than content that is simply steamrolled via class stacking
- Allows more development freedom for content creation and balancing
Switching classes during an instance appears to be one of the two primary reasons for class exclusion. The other reason are the inherent flaws built into a speed run itself.
Does this hurt the overall strength of the armory system? The answer is no. The armory system itself is a great opportunity to build characters, the problem is that the game is setup so you literally have to level every class up to not be excluded. Although the ability of switching during dungeons will be removed, the flexibility and innovation of the armory system is still present via jobs, allowing people who have multiple classes leveled up able to fit ANY spot in the dungeon, and overall increasing the ability for people to enjoy the classes that they prefer/want to play -- rather than mandating they level every single class.
