Wouldn't this be part of the DMG? At least a tactical combat module should be there. As far as a powers framework goes, I do have my doubts, though
Well I did say in less than 10 years


But I have no hope for a powers framework in the DMG, or any time in the near future. I mean, there are bits and pieces of the powers framework throughout the 5e classes, so it's there in that sense. If they actually get to the level of re-writing certain class features to function differently if you're using the tactical rules in the DMG I'll be surprised.
