The Dark Phoenix had a huge impact on the X-men, because she was of them, up until jean died again the memories of the dark phoenix has haunted the xmen whenever jean got a power upgrade and especially when she began calling herself phoenix again. The Shi'ar have been impacted so much that they eradicated the grey genome just to prevent another Dark Phoenix. Cable said that even in the very distant future people told stories about the dark phoenix to frighten young telepaths. She did not crush D'bari, she ate it's sun a very big difference.
Once they figured out how to defeat Onslaught it took little effort to put him down all they had to do was run into him and attack. NOBODY, took dark phoenix down. She went up against all the Xmen, the imperial guard and the warship of the Shi'ar empress, and all they managed to do was buy the consciousness of jean enough time to "end" her life. and yes lets put aside it being crushed in his hand because it's a ridiculous claim.
What happened in Cable's future, means jack shit. The Shi'ar was impacted? plea puh please.
Onslaught lead to Zero Tolerance, thanks to Onslaught the world didn't have much faith in mutants - impact
Every Avenger died, the ones we have now aren't the original 616 heroes - impact
Uatu came to to earth during the Onslaught Saga. Obviously, big business.
Moira said that X-man and dark Phoenix were equals. Onslaught didn't even have to try in order to defeat x-man. Though Moira might've been wrong.
Cassandra Nova killed 16 million mutants, that was over 95% of the mutant population. After that there was nothing but a couple of mutants left.
She wrecked havok in Lilandra's mind, ending in a divorce between her and Xavier.
She crushed most of the shi'ar empire and killed a good number of Imperial Guardians.
She outed Xavier as a mutant and completely wrecked Beast's confidence.
Let me sum it up for you.
Cassandra nova killed more mutants than Dark Phoenix
Cassandra hurt the Shi'ar more than Dark Phoenix
Cassandra caused more problems for the x-men than Dark Phoenix
