Adding the ITCG items to exchange just for them to craft level 40 helmets was funny but sad to see these items already being very rare should serve purpose. id suggest either enabling the good stuff these items craft or just removing them from the exchange as a whole. These items just dilute the already hard and non rewarding exchange we have. By no means am I trying to say everything in the exchange should be amazing but should at least serve purpose as acquiring 50 badges for any mob is a tall task. Even if this has to come with you balancing or nerfing items i still think having them acquirable and balanced is better than just not at all. Adding 30/70%s to this exchange though is a great idea l also think that the 1 turn in a day limit is fine . In my opinion keeping the meso reward at the same rate would be fine with the tradeoff of potentially rolling for better rewards.
thanks for hearing me out - the walking W guava.
