don't forget about planes falling out of the air, hospitals without power, car crashes etc.

And while I agree he had no options as far as saving all mutants, the issue is that he will refuse to fix things. Even if bastion was taken out magneto would refuse to save humanity.

Xaviers view point is that attempted genocide isn't the path to take after an attempted genocide.

Loved Bastion and how demented and unstoppable he came off. Not quite sure how all the XMen can't beat him but then a Sentinel's foot can hold him down. Also if you're going to showcase Iron Man and the Avengers in this episode as, "Guess what kids?!?" and then do essentially Avengers Age of Ultron with Asteroid M instead of Sokovia at the end, why wasn't Iron Man helping in the sky? I get why Daredevil, Captain America and Silver Samurai were just fighting crime on the ground, but are you telling me Tony Stark with all his knowledge of Project Magneto wouldn't understand that he may be needed should the missles not do the job and the Asteroid comes back down on planet Earth that he wouldn't have been on the bottom end with Storm, Rogue and Jean Grey trying to help in some way? I'm not sure why they decided to split the team into different time periods with the gravity core as well, do we need to see the En Saben Nur origin story for Apocalypse when he's already existed in this universe in earlier seasons? I know the comics has the possibility of Wolverine joining him to get his adamantium back, which is likely where they're going with it, but no mention of Onslaught at all, no tease really, Xavier doesn't go ape shit on Magento, just talks to him in his mind for the whole episode, doesn't bottle Magneto's hatred into himself like in the comics. So if you did this, it's going to be really weird pulling Onslaught out and saying, "Remember the finale from last season? We didn't show you, but this entity was created when Xavier did that." Overall Bastion, great, Cyclops, great, Jean Grey Phoenix, kinda outta nowhere and then leaves shortly after it saves her and the team for plot armor sakes. Sucks we have to wait until late 2025 to get the next season.

That is pretty much what the comics did though. There wasn't anything in Fatal Attractions setting up Onslaught save for one line, that could be read either way, about Xavier taking Magneto's hatred away. At the time it was mostly interpreted as Xavier erased it. It wasn't revealed until after Onslaught was introduced nearly 3 years later that Xavier meant that he literally took it into himself.

Anyway, I do agree about the Phoenix thing. It's maybe the only flaw for me. It almost felt like they didn't see the plot hole until it was already animated and tried to throw in a line of dialog to cover it up. It would have helped if they had even come up with a slightly better explanation, like Jean had to let the Phoenix go before it took her over or something. But they basically just had Jean go "LOL the Phoenix left".

Apocalypse should be stranded in the temporal purgatory because he can't rejuvenate anymore because according to TOS the X-Men destroyed his rejuvenation chambers thus he's unable to exist outside of said realm.

Maybe the X-Men that have traveled back and met Apocalypse in his pre-Apocalypse form created a branch Apocalypse we saw on Genosha that the TVA can't prune due to it being in the midst of upheaval currently at the very end?

I admittedly had to look this up because I barely remembered what you were talking about, let alone the shitty 5th season. But apparently in the 5th season Apocalypse came back by inhabiting the body of Fabian Cortez.
