Do not launch just now, there are many things that are yet to be implemented to able to make eldevin a time spending worthy game.
Though you might launch now, i am afraid that withing few weeks, or just a single month the steam community with discard the game as "un-finshed, un-balanced, no end game.".
Suggestions:
- For PVE
1. Guilds
2. Auction House
3. Class balance
4. End game
5. Open world grind-able content
6. End game progression content with variety.
that for pve.
- As for PVP.
1. Need progression for pvp.[ i.e. something you can gain by spending so many hours on it and not just vanity.]
2. Need more CC and counter-CC
3. Need more challenging/interesting class playstyles.
- In general
1. Even though i hate p2w models, im fine with it as your providing everything to anyone who hasn't spent a dime. This may bite you in the a$$ so i suggest you take a look again at your cash shop. Specially at the gold chest, that for some would the ONLY reason not even bothering with playing the game.
2. Need more vanities, yes more awsome,dark,secret,beautiful,shiny,show off,reputation grinded,world boss kills,end game raids[or dungeons in this case], and random open world content vanities
3. Re-model your mounts. This is not a child based MMO and the story quest has no reference to anyone with a flying cape, or a helicopter cycle.
4.Make things more fun, it might be tough to achieve but to able to retain players you need to make your content fun and challenging.
5. Replability. MMOs are not usually one time buy ,finish story quest and move onto other games.
you need to add replay ability so that the players are kept engaged even after they complete/clear the end game content.
The points marked in RED, are imo more important and should be at top of priority than others.
Good luck in your en devours devs. 
place filled with rocket boy and cape man.
