It doesn't matter. Steam is good NOW and Epic isn't, and that's all that matters to a consumer. Epic had all of Steam's history to look at for inspiration and learning so they don't repeat the same mistakes, and then they proceeded to just make all of the mistakes anyways.

I beat her with the Brass Shield and the Nightrider Glaive. I didn't block things I could have easily dodged, but I kept my shield up the whole time to protect me from a bunch of her quick cheap hits. The Glaive is slow and I still got lots of hits in.

I put Vow of the Indomitable on my shield to give me full invincibility during her Water Fowl attack. I'm astonished more people haven't pointed it out. It turns her fight into a cakewalk.

Edit: accidentally called the Brass Shield a greatshield.

I'm not sure why you wouldn't compare them. They have no competition except each other. They're the exact same product, except one has been curated and polished over decades, and the other was seemingly designed by someone who's never used a piece of software before.

No, not even once. It's an inferior launcher to Steam in literally every single way.
