Warrior. Does indeed need something to make you want to play after the first time. Tier 1 talent Hearty meal could make him more engaging by giving him some shielding on his broken seal to utilize provoked anger more often. Combining buffed hearty meal with iron stomach could give him the edge to survive otherwise game ending scenarios. Tier 3 talent strongman has always felt unnecessary to me so that could be something.

More badges or a challenge to test the skill of experienced players. I was not a fan of Grandmaster researcher :D. I would like to see more challenging badges like Golden champion and Grandmaster score chaser.

Endless mode. I always felt it would be cool to adventure outside the dungeon after ascending with a day and night cycle. Something about seeing the sky, clouds and stars on the ascension screen makes you wonder. What does the world outside the dungeon look like?

Extension for the adventure. A final quest for the hero to break apart the Amulet of Yendor to fire, water, nature and dark. Embark on a journey across the land to seal away the amulet into four different locations (Volcano, Icy mountain, jungle and an ancient temple), so the power of the amulet can never be used to do evil ever again.

On the business side of things. A platform that instantly came to my mind is the Nintendo switch. Switch 2 could be coming soon too.

Cant wait for Cleric and Thank you Evan! Shattered has a bright future ahead!
