I can't say much for the other characters but I have been constantly trying to find tech with kenshi, I'm trying to find that magic piece of tech to make him godlike, I still haven't given up on him, but as of right now, he sucks. I won't suggest anyone go near him until someone figures out that magic tech with him, maybe I will find out, maybe pig will, maybe immortal will, maybe darksyde will, but as of right now it is looking grim, as I said I can only truly speak on behalf of kenshi since I have the most experience with him since he is my main, I am just going off the word of many others for the other characters I listed, I don't know enough about Takeda to say anything about him other than I suspect zyphox may be right, that is a big maybe, my conclusion is there, but it may not be accurate, trust me I want kenshi to have that magic tech to boost him up as much as the next guy, but right now it is looking grim. Hell as I type this I'm in the lab with kenshi trying to find something to make him good
