Why the hell are you stating something you have no idea about? Devs haven't said anything about MD, and they probably still have no idea what loot they are going to create for the xpack. It's too soon.
You have a bad habit of stating things that you don't have the slightest knowledge of.
As far as I can tell, El's "purpose" is to spark conversation. It doesn't matter if it's based on false premises, or inciteful, so long as it makes people post and talk, it's a "win". Which imo is kinda toxic, especially when spreading rumors and false information. Even if one of these made up fantasies end up eventually becoming true, that doesn't change the fact that at the moment it's a falsehood as it's just made up at worst, wishful thinking at best. It's really annoying to watch tbh, and frustrating to deal with... do we as a community ignore him until he gets bored and stops? That can work, but a common way to stop bad ideas is to directly oppose it with good ideas / correct the false information asap, and ignoring him also means the falsehoods remain up for all to see and be fooled by. It's a tough spot to be in.
As for the OP... Cannith Crafting is not random. It's the same types of bonuses as found on random-gen gear, but instead of being subservient to RNG, you can customize each item to be exactly what you want it to be. That is a powerful and useful tool.
