VOY's cast was too big, IMO.
TOS got by with only 3 major primaries.
TNG was a nice experiment in a larger cast, so I can forgive them for not using the cast as well they could have since it was the first attempt.
DS9 had access to the entire existing Trekverse so they had enough to spread their cast out and had plenty to do. Even with that some characters still ended up underused or not that important.
VOY should've had a reduced Primary cast. Would've made stories easier to tell and more room for Secondaries.
