Whether it's every three years or 12 months, the result will be the same. Clash of Clans will have, at some point, 20+ town halls, and imagine what new players would go through to catch up. Time reductions are great, but what's the point of town halls such as 1-4? It would be so watered down and fast-paced, that you'd have no time to try out new mechanics or army compositions. In the end, like all games, Supercell will face the same problem - longevity.
I think a way to fix the th spam problem in to change the release time to every two years and focussing on things like balance changes, Graphical improvements and quality of life changes
you can actually upgrade stuff in the lab even when it’s upgrading not sure when the changed it but it’s a feature(what i mean is if you clicked upgrade on the lab but have nothing going in the lab you can still start an upgrade)
Am I the only one that doesn’t have a problem with wall prices? You can obtain loot so easy now and in my experience, walls have always been finished months before hero’s or the lab
if you are playing to max, and not have fun & do the best you can, then you should stop playing. I upgrade to unlock new fun stuff and harder challenges, not to "be max" so that i can stop playing
