Sure, there's a lot of things this game needs, we still don't have an account system and some units could get some sprite/animation updates, but the game still holds it's own till today in terms of gameplay and content amount.
There's still many good additions in the update as well, some units that deserved buffs got them and they are really good now, we finally got an auto battle feature, lot's of rewards were given from missions and logins and the new SSR is a very fun to use unit, which is way more important than the fact that she's just a copy of an already existing character.
Also don't forget about the additions we got in the last few months, like the new passive system, the event UI update and the new bosses and F2P units.
This update gives me hope that the game will just get better and better in the future, I at least hope that's the case as this is the only good mobile game with the Fate/ IP.
Also the collab is very enjoyable even though Its just a re-run, just wish I got more time to save for rolls.
