Why not just make everyone a DPS?

There is so much wrong with this. Crit has diminishing returns and isn't the most optimal off stat for all jobs.

I don't disagree with the general spirit of your post but do be careful with the facts you lay down.

There is no actual diminishing return as in each point of crit gives exactly the same % of crit chance, this doesn't change no matter how high you go in crit. The stat value doesn't change and each point is as good as the previous one. Crit is as linear as any other stat in this game.

The "diminishing return" people talk about is due to forced crits from things like Bootshine/Life Surge and crit buffs like Internal Release and Abandon, etc. This affects crit stat weight, not crit's % chance per point.
