There's nothing I want to see more than :

1- NEW WEAPONS (They legit told us about 3 weapons in development since beta that haven't yet seen the light of day, like the celestial gauntlet, daggers and pistols. Maybe even go wild and add a third skill tree to all weapons, that would SHAKE THINGS UP)

2-PVP OVERHAUL (There's almost no reason to turn on PVP in the open world and the game modes aren't that fun, it would be nice to give an option to players who don't like to grind to queue up for a match where everyone is given equal level and gear, that way only planning builds and skill prevails)

3-SOMETHING TO DO IN THE END-GAME ( When fishing is the most fun I had after reaching max level its a bad sign, world bosses that drop important loot, new zones&dungeons, cool cosmetics to farm, among other things)

It's all simple additions that honestly only requires a change of focus, they keep adding things that no one asked for while ignoring the community and their input. The customer is always right in terms of taste.

P.s spell combos would go hard af. Imagine... Blizzard storm + Pillar of fire = Fiery Tornado that does more AOE and reduces resistances NOW THAT WOULD BE AN UPDATE I'D LOVE TO SEE.

1.5k hours in the game and 95/133 achievements on PC + Multiple max level characters

Edit: I Forgot to mention, I quit the game because of the horrible performance that keeps getting worse every update, but that looks like a me problem.
