Your scenario seems a little improbable to me, at least for a casual player. I’d say I’m a little more than a casual player in that every day, no matter what, I log in at least once, generally play for about an hour most days and once or twice a week enjoy a lengthier session of 3-5 hours. Getting to rank 1 each week is a no-brainer, but to log in 8 times a day on console would require me bringing my PS4 to work, or getting up a couple times in the middle of the night to log in. Neither of these would be healthy behaviours.
Your 16-18 glory per tribute sounds a little high as well, but I’m sure you’ve run the numbers on that. I assume that is all kingdoms at level 10, which I have not yet achieved (13 at 10 with the remainder around 6 or 7, increasing one at a time to maximum). Also, all kingdoms to power level 3 is a pretty end-game scenario. I’m level 260 and just got my first to 3 gold stars this past week. Only one other at 2 gold stars and I’ve made a conscious effort to pick all the low-hanging fruit.
Also, 30-60 glory per map seems a bit high, but perhaps you’re very good at that. The reward distribution is pretty random, but when I average around 60 moves, I feel like i see anywhere from 8 to 35 glory. 60 would be an extraordinary number for me. I have the 2 vault trophy (achieved after the drop to 8 starting turns), so its not like I suck at that minigame, either.
