I'm quite curious to hear what you mean with "pretty english words". At the very least I don't go around defining what other people say "insane retarded" (lol).

he whole point to xiv if that you can built this power character using abilities/job traits from other class related and become powerful.
Who ever said that?

The point of FFXIV Isn't power. It's versatility.
An ability can still be useful (IE: contributing to versatility) even if it's not used at it's full power.

There's plenty reason to do that despote needing full parties and alliances for high level encounters. Being a versatile character means that you can SUPPORT other characters in their main roles (IE: throwing in a heal if the healer is under too much pressure, or raising your damage sensibly to raise the damage output of the DDs, without overshadowing them) when in party, and that you can face a wider variety of situations when you're solo.

Are you seriously telling me that, according to you, the point of FFXIV is being able to solo everything?
