At the moment, and I'm not certain because we may be missing something on how to play that spec, that goal doesn't seem to have been reached because only on very short bursts that last for a few seconds Arcane seems viable, mainly for levelling.
They overdesigned it I believe. There would be little drawbacks in giving the progress of artifact power and relics to all specs simultaneously. The spec lore progression would still remain and the balance of utilities wouldn't have to be extreme.
