"The Gorosei are failing to defeat/kill the SHs and others! Fucking trash!"
Yeah because it's not like they have plot armor and it's also not like the Gorosei are being held back.
"The Gorosei couldn't stop Vegapunk's message quickly! Fucking trash!"
Yeah because the Gorosei somehow knew where the den den mushi would be located, even York didn't know where it was at first.
"The Gorosei couldn't accomplish a single thing! Fucking trash!"
I guess you forgot about the Gorosei being able to locate Punk Records, the Mother Flame, freeing York, they also were able to accomplish their mission on killing Vegapunk thanks to Kizaru, and while they couldn't fully stop Vegapunk's message, they were at the very least able to stop Vegapunk from revealing any important information about the Will of D.
They also freed the Cipher Pol Agends and the Seraphims as well.
"But the Gorosei are weak? Uhhhh trash?"
All five Gorosei have CoC and awakening, their haki were hyped up, Jinbe hyped up Mars's haki in a similar way to how he hyped up Shanks's haki.
G5 Luffy couldn't do anything to Warcury and he along with Dorry and Brogy were running away from him.
Luffy, Bonney, Sanji, and Franky needed to team up just to send Mars away.
Nusjuro easily cut the Labophase in a single slice.
