Anyone feel that a lot of legendary Pokemon are just phoned in? Personally I think that a legendary Pokemon should have impact on the world, but some aren't even needed.

For example:
Taoism Trio: Do we really need a Pokemon of ideals and truth?
Swords of Justice: Don't the legendary beats do their job?
Forces of Nature: Doesn't the legendary trio do their job?
Mortality trio: The problem with these guys is that they don't do anything. The only time they became relevant was with Team flare, because they've been asleep the entire time with no history of them effecting the world. And Zyguarde job is already been taken by Rayquaza, and it probably does it better.

Dream duo: Do we really need a legendary of good and bad dreams?

And now we're up to the point where they're not even legendaries, just rare to our world.
