I've been thinking about if it wouldn't be more fun for players if the T50 worked in such a way that the score you accumulated during a time period was what counted, instead of overall score. This would work like the ladder system in Diablo II, being reset every other month or so. Or maybe just twice a year, whatever works best for Elements.
Perhaps the score gain from the different CPU levels would have to be adjusted so that it's not completely full of just Elder-grinders, I dunno. In any case, getting to 130k these days takes a very long time, and the guys in T50 aren't getting less score; they're getting more. Some chance at glory for guys who still have played several months might be nice for the overall popularity of the game.
If the long-time holders of T50 spots don't like this idea, another idea is to have two separate T50's. One that's based on score accumulated during a set period (perhaps called Ladder), and one permanent like the one we have now (yes, I know it's been reset at least once in the past). I'm sure the devs can think of something that works decently for everyone while making this game more popular and liked.
