I really like this suggestion. Instead of thinking of levels in just 1 dimension (1 to 50), there would be several different dimensions, each with levels 1 to 50. So instead of having the mentality of “from level 1 to 100” (and levels losing their gamifying effect behind it), one would still think of “from level 1 to 50 to conquer this floor” (yes, like a game with dungeons ). Being in the 2nd floor and level 1 would still give an idea of superiority over being level 50 in the 1st floor.
I think it could work.
Right now, I’m in the same level as some people with almost 3 times less master cards. Not that it bothers me personally, but I don’t think it makes sense to be like that. On the other hand, you shouldn’t need to go through hell in order to level up. I think the above proposal could solve it.
