If you could make impovements to Deep dungeon...

[Teraluna]

1. Put it in the Duty Finder as well as the PF
2. Remove the RNG - this is a must.
3. Saved every 5 lvls
4. Increase time for light parties (3-1 people) +10/+20/+30mins
5. Introduce decent map UI
6. Introduce decent character UI
6. Make the UI's easily scalable
7. Allow multiple attempts at boss. People need to learn the boss mechanics - which I imagine will get harsher in future levels - so treat these the same as dungeon bosses: fail = retry.

Rng causes widespread player dissatisfaction. It may be acceptable in some cultures, and I appreciate the development team may be from one of these.
But this is the West, with a different outlook on effort v reward. It's just not well accepted here.

Recall Aion's weapon and gear enhancement system - RNG at it's worst. They changed it - but too late. By then scores of people had given up trying to enhance their gear, quickly followed by giving up on the game. Went ftp not long after.

This game shouldn't be making the same mistakes on effort v reward.
