Why not rebalance all Job Roles based on Special Stats & Abilities?

[Kaliesto]

Like for Tanks:

Give Paladin the Best Defense for itself & others, but lacking in Physical Attack with some moderate Magic Attack Damage.

Give Warrior the Highest Physical Attack with single hits & AOEs, but lacking Defense & Healing Buffs (much as I like them right now), so they would have to work in tandem with Healers more often.

Give Dark Knight the highest Magic Attack with some low Physical attack.

Make Gunbreaker the Jack of all Trades, but master of none (low-moderate-high based on Critical Hit for Damage, and Healing/Buffs tied to other stats that affect their buff timer & Healing numbers).

==========

White Mage:

Highest Magical Attack & Healing in the game, but lacking in other stats & MP Pool, and it would be more susceptible to KOs if not careful.

Scholar:

Low Magical Attack, but moderate buffs & Healing.

Astrologian:

Best Magical/Physical Attack buffs in the Healer Roles with low Damage & low-moderate Healing, but it should get re-worked to bit tbh as it works now.

Sage:

Best Physical/Magical Defense Buffs, and with some low-moderate Damage, but can attack faster than all the other Healer Roles.

=========

(so I know some of these classes already kind of work like that, but maybe put more emphasis on it)?
