Ideally, a 5E would have multiple types of characters, each using different mechanics, to capture an even larger segment of the potential playerbase. Instead of everyone functioning on a three tier 'daily, per encounter and at will' scheme, different classes and roles would function differently tactically, with some being resource-management base, some being 'all day long' based, and some using other schema entirely.
We could call one a 'Warlock,' and it could be an 'all day long' sort of character, while another could be called a 'Wizard' and have a finite number of spell slots changeable daily, and another could be called a 'Psion' and have the ability to micromanage individual power uses via different gradations of expenditure of some finite resource pool we'll call 'power points.' Other classes could have different sorts of situational adjustments, so that a 'Rogue' might be able to outdamage many other classes, but only if certain pre-conditions are met, and these pre-conditions would vary from class to class, with 'Scouts' getting bonuses when fulfilling another condition, 'Rangers' getting bonuses against certain types of target, etc., etc.
It will be brilliant! There could be classes to appeal to each different style of play!
That sounds awesome, I'd totally play a game like that!
