@RavenSupreme - Okay, that's it, you're saying Ban wins when you're seemingly unaware of Doflamingos awakening capabilities? And you have the gull to passively insult my statement? Don't even start.
Let's begin with answering all of your questions:
1) Yes, he can turn the ground to threads and he has shown this for several chapters against Luffy: http://www.***********.net/one-piece/785/8, http://www.***********.net/one-piece/785/16, http://www.***********.net/one-piece/790/6 -- just FYI, his range with his threads reaches dozens of kilometers via Overheat, Birdcage, Spiderthread, Sky road, and those are not his awakened powers. His awakening turned a huge chunk of Dressrosa into threads while he was fighting Luffy. He did this while focusing on repairing his destroyed Organs.
2) I do expect Ban to take the slashes especially after he is incapacitated by his own ability and is unable to move. He can only use HF within a small radius as compared to Doflamingo's thread power, which has streched over dozens of kilometers. Ban doesn't INSTANTLY REGENERATE unless you want to argue that ridiculous BS (saying that Doflamingo's ability is NLF? No). In the instant he is sliced apart, Doflamingo can simply take him underground far enough to the bedrock and leave his body there, where he would not be able to escape. Wanna know why? He would not be able to move a single finger or completely regenerate when his body is put inside of bedrock many many kilometers under the ground.
3) ^ so no, Ban will never escape unless you want to suggest his City level (Can't use HF when he is way beyond his ability radius when that far under ground) physical abilities can effortlessly lift billions+ of tons.
Ban doesn't scale to Monspeit. Ban only scales to Base Galan, who he can become more than HALF as powerful, which is STILL Mountain level. Doflamingo would remain Small Island+. Ban should only be 7-A via scaling to Base Galan, who should honestly, as you said in the other thread, be around the High 7-A area.
