These are base values, they grow a lot with ilvl. When I look at Azerite traits at proper ilvl throughput ones have equal to more effect than Legion Legendaries have.
As for state of Beta, it's nothing new - in Legion Beta we had more than plenty features broken or half complete at the very same point of time.
Class campaigns, for example, were half-broken very deep in Beta to the point where you could not progress even the initial quest line unlocking the Order Hall. Result? One of the best launches in WoW history.
