Does Shredder have too many lieutenants

[PApagreg]

I just realized something(well actually not really I was thinking about this for a long time) Shredder has too many lieutenants what I mean by it is that it feels like the writers gives Shredder too many henchmen that even they don't know what to do with and their skills are sometimes redundant.

Ex
Xever was a caporia fighter who is not only a skilled thief but also has ties with New York's underworld and tends to keep the Purple Dragons in line but a few seasons later we have Zeck who is also master thief and a season later we have Hun the guy who keeps the purple dragons in line. It feels as if the writers are too focused on making toys and figures instead of wanting a good show and to add salt to the wound Zeck and Hun aren't anything like their counterparts. Now don't get me wrong writers are free to have different interpretations with their respected incarnation but with the amount of characterzation the Nick versions Hun and Zeck have its the equivalent of making Mikey a punisher like vigilante
