I think it's way too soon to say it lowers skill gap.
The one thing that can be said about it is that will cause the meta to be completely different than every other competitive shooter out. Right now, everyone is playing it like a run n gun game but as players get used to the mechanics of the supers, it will affect the way people travel the map, how people control areas of the map, and as a result counters will be found, etc..
Now maybe the maybe will be unsatisfying or maybe it will be fun. That we'll have to wait and see on. But it's definitely too early to say it lacks skill. Give people time to play with it and figure it out first.
