nearly every aspect of the game is now scaled through might: the rewards from expedition, the rewards from quests (you don't even get all the quests until ~45k might), the daily rewards—you can scoff at these, but the player with 45.9k might getting the full quests is also banking a free 1200 gems, 2400 shards, 135000 hb per month vs. roughly 240/0/1500 for someone with 7k might—hero strength in arena and expeditions, etc, etc.
the rewards for expedition are TEN times higher for my main account vs my smurf, and since the update, it's pretty much a joke to beat at any level. also, I frequently raid bases with 400-900k gold or mana, which I can't even use because the rewards from doing the simple quest board are overabundant. at low might you have to hit dozens of bases to make the same flow, and while it might be super easy it's also boring and repetitive. and for what it's worth, higher might players will usually wipe you out in one go leaving you with a 10 hour shield as opposed to weaker players picking at your mines for hours until someone shields you.
you guys are actually doing more work for a fraction of the benefits. if you level the right way, you shouldn't run into problems raising enough gold or raiding. if you hit a lull, buy and sell statues for a while to maintain gold for upgrades.
