That's all still pretty basic in Karate and believe me, you ain't getting any praise from the MMA crowd with this.
As correctly pointed out by
@rmongler this is only suitable for point kumite. I will add that point kumite is a very
modern invention and Karate was
never intended for this kind of competition. If you look at old Okinawan bunkai it is
never one-shotting multiple opponents (like it is presented nowadays) but instead it is a
sequence of strikes, grabs, locks and throws done on
one opponent. Combinations and follow ups are the core of kata and the original art. The
"ikken hissatsu" (kill with one blow) approach is actually borrowed from Kendo. More on the same here:

Of course training for point kumite has its benefits - it can produce superb timing, defense and footwork - but it takes a
very high level practitioner to make it work in MMA (Chinzo and Lyoto Machida, Wonderboy etc.) and said practitioners still must train continuous full-contact to adapt and adjust.
