Why should the yeast supplied not be good enough ?????
Surely the kit makers are going to supply a good yeast not a duff one ????
It would not be in their interest to provide a poor yeast would it ??
That would make sense wouldn't it . . . unfortunately that is really not the case. In the long distant past they have supplied bread yeast, and even now they generally are supplying a 'generic' ale yeast. . . even if it is a lager kit. The yeast is stored under the cap, in all temperatures for potentially a long period of time . . . so it is probably well past its best when you come to use it. Also the qty supplied does not meet best practice WRT pitching rates, being at least half that required for a proper pitching rate . . . yes they get away with it, but why do many kit beers taste 'yeasty'?
Using a separate sachet of a named variety of yeast can really make an improvement in the beer that is made. Often it is in the shop for less time, and some shops now keep it refrigerated, and most are now around 11g meaning that you pitch at the proper rate . . . or at least close to it.
