The game has developed quite abit but the number of badges hasn't moved.. So since I'm bored, I offer some suggestions..
Rise of heros: Achieve level 60 with 3 heros. 4 badges.
Quest Master: Complete Chapter 4. 4 badges. 100 gems. Shadow Monster Avatar.
Quest Master: Complete Chapter 5. 5 badges. 150 gems. Mad Serpant Avatar.
Boss Slayer: Deal 300k damage to a boss in Pet Rescue in a single fight. 5 badges. 150 gems. New avatar frame.
Boss Slayer: Deal 100k damage in a guild dungeon in a single fight. 5 badges. Dragon Avatar.
Also consider a new tab for grindy type achievements. You can call it "dedication" or whatever. Number of quests runs, number of raid tokens used, heros at a particular fame tier, etc. You can start everyone's count at zero for the numbers game.
129 is a seriously weird number to stop at..
