That’s is exactly why you should play the game a bit longer first. Everything you said already exists in other games like Fristborn and LDOE.
I like this game being different and have different kind of coop with allies.
I don’t think selling or trading will ever be an option as all it takes to be OP in your situation is ask someone from the top players to make you one gun. And all you have to do is just fix it. Which will break your experience in the lower levels and enjoyment of growth.
I’m lvl 110 and I know for a fact, that you can just do quests and get you silver to get more energy. Plus do some CT for additional silver and sugar for your horse.
After you get your horse, you will have more energy options and stuff starts opening up for you more. Level up and understand what the game is first, then suggest new features to add
