Alright, let’s talk about what these S3 governing+support stones or PoE skill+support gems are, what D3 runes are, and what people asking for more outer-tree nodes in D4 is about. Really they are different forms of the same concept - take a skill and modify it a number of ways to offer players greater choice. There is a consensus variety is a good thing. Where I go off-trail is in recognizing that as long as you have a very limited number of active slots (i.e. a bottleneck) that tend to always result in basic gameplay more choice doesn’t mean a much better gaming experience. It is beneficial but it only goes so far.
So I don’t want them reworking anything, especially when the basic option needs to continue to exist. They can and will keep doing the traditional stuff that brings nothing new. What I want them to do is add on top of it button remapping so as to multiply the number of active slots. From there you can go into multi-level containment structures of additional skills and variations to execute from on the fly - which is what this particular post expounds - or you can do a more introductory/intermediate implementation of runes and runewords where you limit the additional remapping levels to one or two and tie them directly to pre-existing skills. This is by no means easy but it’s also doable, and unlike most of their ideas I think has significant big-picture potential. Or as HeWhoIsHim would unartfully put it:
