The main one i want to get to is:
1. Increase in penya cap
Reason being i tried selling 1320 diamonds = 6,600,000p surpassing the 2.3b cap, lost both 1320 diamonds and money
other suggestions:
2. Making the hero skill easier to level up
3. Larger inventory [even with the bags]
4. Making the bag like the inventory [can use items in the bag]
5. TOWN INVASION
Also unlimited amount of buffs if it hasn't already been implemented.
