"Is it impossible for you to understand that there are valid criticisms about Mass Effect 3 and its ending?"

If there are "valid criticisms", then use them, not baseless complaints.

"his problem should have never been mentioned there."

So it would have been better if the series simply left the entire reason for the Reapers' cycles in the dark? Ignoring the build-up from Harbinger's dialogue throughout ME2?

"The last five minutes of a story is the absolute worst time to introduce new important elements to the story."

Human-Reaper.

"yes the conflict did EXIST in the series beforehand, it just wasn't at the forefront enough to constitute it to be the MAIN conflict/theme."

Exactly—it's not the "MAIN conflict". The main conflict is what you were trying to do for the entirety of the game: stop the Reapers. Considering how only one choice actually addresses the Catalyst's problem—not that there are no other reasons for choosing Synthesis—and all of the choices address the Reapers, it's painfully obvious what problem you're primarily trying to resolve in the ending.
