Let me elaborate on what I mean by "clean up".
There are currently a few systems, blocks and items that are holdovers from previous versions that may or may not be cluttering up the mod without actually adding anything.
Tubes, for example, might fall into this category. I like tubes, but a lot of people seem to dislike them and they are obviously not very easy to use. The new transfusers are easy to use and it stands to reason that they can easily replace tubes completely. If they should is a different matter and that is why I put up the poll.
Another example is something a bit more abstract: Does vis also need to follow the aspect system?
(Note: I'm specifically talking about vis here, not essentia.)
Think about it for a bit. Vis is just a measure of magical energy and from a gameplay perspective acts as a gating mechanic. Want to craft gizmo A? Well, you need X amount of vis in your wand to do it.
Its second purpose is to be a limited resource and something you must be careful to not overuse. Overuse it and you get flux.
Neither of those purposes require there to be 6 different types of it. It is literally just flavour.
In theory you could make it so that there is just one generic type of vis. It will make things more boring, but how much will you really be losing? Purely from a code perspective it will be a big win in performance and simplicity. It will speed up aura calculations almost 6 times.
Will you be losing out on gameplay? Good question and that is something to consider.
I think having two aspected systems (vis and essentia) is redundant and doesn't add much depth from either a lore or gameplay perspective. Everything you currently need 'aspected' vis to do can be replaced with either simply 'pure' vis or a combination of vis and essentia. Essentia covers the building blocks / crafting gameplay while vis can cover all power management and gating aspects of play. The fun of essentia comes from combining different aspects to make different things, the fun from vis comes from managing the power system and balancing output vs. flux.
I can't think of a compelling reason from a gameplay perspective to also have aspects apply to vis. Wand focuses that use aspected vis? Well now charge the focus with the proper type of essentia (building block/resource system) and charge the wand core with pure vis (power system), casting the spell will consume both vis and essentia. Perhaps the spell itself is influenced by the essentia used to charge the focus. Have the infernal furnace and arcane bore draw from both the vis aura and essentia sources if it is available. Many arcane workbench recipes could easily be replaced with a pure vis cost, ones that can't from a lore perspective can require a phial of the proper essentia.
I seriously cannot think of one aspect of gameplay that would suffer or become simplistic (perhaps simpler but that is not a bad thing) due to vis losing its aspects. There is nothing to lose that couldn't be replaced by using the essentia system since the two systems are currently extremely redundant.
