A Trading System would be a great addition to this game. The Random Loot that causes demand for even some 3-star characters, The evolution system, and the Heronium store, are perfect reasons why a Trading system would let different levels of players get what they want from other players.
Since the crates are random everyone has different characters. This means that a Level 2 can have a Chesterfield and a level 75 could possibly not have a Chesterfield. Many players are on a quest to get/max out all the heroes and Trading would be a great way to achieve this. The higher level player can trade items, skill points, energy bucks literally anything in their possession for the Chesterfield to complete their collection. Or if a Mid-Game player wants a hero crate exclusive character like Ifrit, they could trade with another player.
The Evolution System:
Everyone knows that you need a crazy amount of frags to get a 10-star hero. For people that want to progress quickly it’s not ideal to farm the stores or quick play the hard mission (Or not even able to get them because the hero is a hero crate exclusive) the trading system would be perfect. These players could trade heroes they own or other items of importance for the hero they want fragments for.
The Heronium Store:
A lot of the Hero Hunters community is kept out of the Heronium store because of its expensive need of a 10-star hero. Many of us simply don’t have the resources or time to achieve that in the near future because of how demanding it is. These players can trade with higher level players with multiple 10-star heroes or a player with the same hero that you want to get to 10 stars.
Some Potential Problems and How to Fix Them:
One main problem that always happens with trading is scamming. No matter how secure the system, there are always some cases of scamming. Some ways to prevent this is to have a value meter. It takes a valuation of the items each person is offering. Some simpler things are is to have a pop up confirming the deal and a 10-second phase to cancel the deal after accepting it. We all know that HotHead is here to make money so trading doesn’t have to be 100% free (I have to please both parties lol). It could cost 100 gold or so from each trader. If they want to milk us a bit more they can make it a VIP 1 feature.
Overall, Trading would be a great feature to add to Hero Hunters because it would enable the player base to access the Heronium store a bit easier, allow gaining hero fragments more convenient, and it will also work with the random loot tables perfectly.
I thought about this after writing the entire thing so I’m going to add it here: It will also help people that need to promote their characters to different ranks (Bronze, Silver, Gold, Platinum) because a common problem is that people run out of energy and can’t play mission anymore. The trading system will act as a workaround because these players can trade for the things they need to promote their heroes.
