The best idea I’ve seen for the whole thing is to take some amount of all “common” resources (gold, souls, traitstones, possibly even glory/maps) and use them all along with the “rare” bottleneck resource (gems, the main thing that controls how many quality troops you get) and have a system to either craft troops directly, greatly increase your chance at getting specific troops, or greatly reduce drops you don’t need. The idea would be that everyone would still be getting roughly the same amount of troops, but the amount of useless drops would be reduced for those that have the extra to spend and that you would still be able to “farm” and move you toward a goal in some way.
As it stands now, the problem is threefold - theres a bunch of resources that you can only spend so much of without either not having anything to spend on anymore or taking a HUGE hit for your return on investment for time, an ever increasing random troop drop pools, and a heavily softcapped amount of troop resources per week available. While it might be an “endgame” only problem now, it will eventually be a problem for anyone continually playing the game at all but the most casual level.
As much as I’d like to personally, we cant simply remove all the mythic +4s from the drop pool - it would be far easy to get new stuff to mythic for a minimal expenditure (less that is obtained per week from just guild tasks eventually, which actually would break the economy for everyone, not just the 0.01%). And allowing direct exchange of the most common “farmable” stuff for the most rare would break their distribution model - even at a quarter million souls each, I could have both my missing Mythics inside a week without any additional expenditure. However, if they cost 2-2.5k gems in addition to some other stuff, I’d be out the same amount of gems it would take me to get a random mythic to drop on average (in addition to at least half a dozen potential legendaries and 50+ epics and whatever common resources it would take to “craft”) - they’d “cost” about the same as they did during their exclusive week, with additional expenditure for specificity being much more reasonable and coming from my other resources and not my gems. Such an expenditure would have anyone not in a top guild during the old “broken” economy risk not getting the next exclusive mythic, which would leave them with another missing mythic. Those that did have the extra resources are going to have these mythics anyways. If I needed to “craft” special keys that always gave me something I “needed” that required all resources (or that at least weighted toward stuff I didn’t) that would also be acceptable.
