Edit2: tldr keep everything the same from dd1, but get rid of buff beams, nerf the wheel, lt's, and dsts, then add a hero deck and auto collect.
Want i want:
Pets to be returned from dd1 and useful
Pets rewarded in survival like in dd1
Dd1 tavern. Dd2's was too big imo
A trading scene
Cosmetic set bonuses
Acc that give stats and i can see on my hero
Skins that affect the heroes stats
The eternia shard maps
Being able to drop items on my tavern floor.
A kick button for host
Challenge maps (like volcanic eruption)
Edit: Build timers (almost forgot this)
What I don't want
Whatever the social hub thing was
Tha hatching eggs for pets
Feeding the pets
Pets growing affection
Pets unlocking abilities as they grow
Basically the entire pet system from dd2. It was annoying.
Iwpr or whatever that gear score was
Vote to kick
I'm probably missing some stuff from dd2 i didn't like but this covers a lot of it.
