Would be neat to see different types of equipment in the game. Maybe something broke down by color code. White is normal, green is rare,yellow legendary, etc etc. As you get equipment of different colors or rareness they would have more attributes or stats.
Also would be neat to find pieces of equipment or pets randomly in chests.
I just wish they'd add stronger equipment for higher levels in each world. i say this because i really don't like being forced to dress to the theme of a world for better stats.
