One note first off. A lot of the criticisms seem to come from trying to apply a knife to a job other than it was designed to do. Bushcrafty knives suck as fighting knives, and fighting knives suck at bushcrafting tasks. However, you can use either type for either application. The other problem I see is a lot of people don't like a knife, or say it won't do [X], because they want the tool to do the job the way they want, rather than learn to use the tool. I'm just saying this because I was guilty of both things for a long time. Now, if something doesn't work the way I want it to, I ask "what can I change about how I do things to work the way the tool wants to?".
You might be surprised at how well that works out. Sometimes it's a small change that's required in your way of doing things, or in the tool itself to get it to work. For instance, Busse gets a lot of flak for his grinds. Well, the obtuse, "toothy" edge is exactly what you want if you have to use your knife as a breaching tool/rescue tool, and cut a lot of nylon strapping, as you might have to do if you're in the military, an LEO or a SAR member. Like someone pointed out, it's "Busse Combat", not "Busse Bushcraft". However, I've done nothing more than sharpen some of the thicker Busses with a fine stone and then strop the edge --
maintaining the factory edge geometry, and they sail through wood now. They even cut meat like a laser. Such a small change.
Now to pretend this post is on topic

. . .
I dislike tiny handles on knives. I see no point to a handle that I can only get two or three fingers on.
I don't like skeletonized handles or "neck knives". I understand why they are that way, but for me, it's too much compromise on ease of use for too little in weight and bulk savings.
I don't particularly like big choils, but do like a sharpening notch (preferrably round so it doesn't create stress risers).
