My feedback, what I would like to be changed
Questing
None cares about dialog paths.
Let players just accept quests.
AI, Mobs
Change mobs attack distance.
They should see you a bit farther.
I don't know if mobs tagging is a thing, but I recommend including it.
Death penalty
Add respawn timer, or wow like go to the corps system to prevent people from respawning too fast and killing bosses without any penalty.
Wipes should be a normal thing.
Social emotes
I recommend adding if there aren't social emotes.
Game play combat, movement
Player should be able to noclip via another player. I don't see any reason why not. This only creates problems as body blocking trolls and exploits. If the player wants to stop you he should attack you by rooting you or slow you down by dizziness or what not.
Also watching 4k gameplay video I saw you get stuck in the rock. I would recommend you to activate noclip between doodads and player if he stuck. (I assume you guys will sort it out)
Raiding, dungeons, PVE
Add a distribution system for loot.
Simple need/greed/pass system for dungeons (for small groups) and leader loot distribution, and roll system for raids.
Some boss spells should be interruptable.
PVP
Skills should be interruptable with fear and so on.
Also, don't forget to add various dot skills to the game. That would create a need for PVP orientated enchants, and items for fire, shadow, cold resistance and so on.
Art direction (spicy opinion)
Guys can you make a bit settle art direction. Not everyone likes Linage, hentai, and karate, ninja, anime swinging, or casting skills. Melee, casting attacks should be simple and feel hitting hard, but not over the top anime bs. (more realistic please)
You should feel more to the ground.
Make simpler and poorer looking gear and items, mounts. Not everyone should be with the golden set riding rainbow horse.
Low-level stuff should be more to ground. Also, mounts should be more simplistic. Simple brown, black, gray horses or griffins.
Only after dungeons and raids, you should get that spicy and rare looking content.
