See, World of Warcraft figured this shit out almost two decades ago now. Back in the day, they wanted to encourage more regular, daily logins so they added an "unrested XP penalty" where you would gain less experience points after earning a certain amount every day. Players absolutely hated this. They fixed the problem by saying the initial, normal XP gain was a "rested XP bonus", while the penalized XP gain was just the "normal" XP gain, while in reality, none of the numbers actually changed, they still rolled out an XP penalty dressed up like a bonus
If they just said "We'll give you a discount if you show up while it's dead" while quietly jacking up all the prices, people probably would have loved that shit
