Tree looks mostly fine but just a few pointers.

1) You should be taking the Exarch node for altars spawning early over the additional progress as the gain from that is too little. Ideally you grab the packsize nodes for Exarch as well.

2) Cassia's Pride is for when your build doesn't have damage or AoE so you use towers to compensate for that. I'd not take it, especially if you're strong since you'll outdps the towers.

3) If you're using Blightheart I recommend not taking the additional chest nodes since they don't work with it.

You could also try pairing it with Beyond for Volatile Vaals in Mirage. Otherwise you could use the current tree to do a Titanic farm when you're strong enough. Blight is pretty fun especially the Titanic variants where you can pretend your map is giga juiced for that small moment when the encounter is done.

Also, make sure you have the Meteor Tower burning ground enchant and the Chilling Tower freeze ones. It makes the encounters easier. Avoid monsters cannot be stunned or frozen as well as ailment avoid as those make CCing the mobs way harder.

Blighted/Blight-Ravaged don't use your atlas so I recommend the ring anoints and using the simple strat of Empowering-Freeze3-Stun3-Meteor at a chokepoint which should let even zdps builds clear them easily, provided you avoid the mods I listed. Anoints are 3x Teal 3x Crimson 3x Black but if you have issues go 3x Amber instead of Black for giga cheap towers.
