The Crimson Binome
Hero
Have you seen Iron Heroes? That about wraps up the whole system, really. Half of the martial classes have unique resources which they build in semi-unique ways and expend to do cool moves. And between Monte Cook and Mike Mearls, it's about as D&D (3.5-era) as you can possibly get.Do you think the D&D audience will accept a mundane (non-magical) class which has a resource that powers abilities?
Different people have different thresholds for what they can accept, though. I might be fine with Iron Heroes' Archer class, and its Aim tokens that it spends to power their shot maneuvers, but I can't possibly accept Pathfinder's Gunslinger class with its Grit pool.
That's because my objection has nothing to do with fighters having nice things, and everything to do with meta-gaming. Grit is just a narrative construct that's all about the Gunslinger being so cool that the laws of nature no longer apply, where Aim actually has in-world meaning as a measure of the Archer's ability to aim very well.
Either way, it's kind of a moot point. You can't really do short-term resources in Next, because battle is over too quickly in all but the most-elaborate of combats.
