This vid is 11 minutes long. It details basic changes in Thaumcraft 4.2. Outside of the written information you find on the forums, HaighYorkie is the BEST source for Thaumcraft info. Period.
Oh man, I love modded Minecraft sometimes. The logic is just flawless. After all, what's the best way to deal with serious competition than NERFING YOUR MOD TO HELL?
But really, this is just sad. That was an 11-minute video of nerfs and literally nothing else. I would accept Warp if you could get rid of it, even if it was only in the late-game and really expensive. But NOPE. It also sounds like if you turn off Warp you don't get the new Eldrich stuff (could be wrong here). Azanor clearly didn't learn from IC0.2 that making purely annoying elements and adding them to old objects that everyone liked is bad.
