Dunno about those new pokes but normal/ghost seems pretty Op If I can recall my match ups. Only weak to Dark and immune to fighting/ghost plus other resistances.
edit: maybe bug is good against It too but I dont remember
I recall that bug was a beastly physical attacking type with great pokes like Heracross, Pinsir and specially Scizor (and great moves like Megahorn). Maybe they makes them frail glass cannons to balance out the typing.
