What are you playing?

Not sure if I'll get Dark Souls though because I don't like some of the changes I've read that they made. No Nexus? Can't repair equipment? There were more but it just sounds... not for me.

Demon's Souls is easier than Dark Souls, though. DeS is awesome and has lots of great things, but DaS is just so much better overall. It would be silly to not play it if you enjoyed DeS. Yeah, there is no Nexus but that's because Dark Souls is much larger and open world. I love the Nexus don't get me wrong but it doesn't make the game in any way. DeS feels really short after DaS. I have no idea where you heard you can't repair equipment, but you can. At any Bonfire (think Archstones, but with many functions you'd normally find in the Nexus). Just have to buy the repair box, which can be done before you ever need to repair anything.

False Allant punishes aggression. Just don't be aggressive and you'll realize he's a pushover. All of his attacks are easily dodged if you keep a safe distance and keep moving. He brings himself right to you constantly. Wait to attack after he does so. There's a safe period to attack after nearly all of those situations. Attack once and back off. Repeat. Don't try destroying him or you will be destroyed. Or you could just be cheap with magic.
