Shadow Power Source Done Right: A community homebrew proposal
Since the new preview of Heroes of Shadow has effectively proven that Wizards has delivered the killshot to a true Shadow Power Source, and it is a well-known fact that many of us in this community and elsewhere are highly disappointed about their choice to destroy the Shadow source and leave us with diluted half-classes which don't do justice to the full potential the Shadow Source's archetypes, I have taken it upon myself to make this thread to present a proposal to the fan community.
I propose that we, as a group, cooperate to create three or more full 1-30 Shadow classes which we can all be satisfied with, and enjoy playing. My intention is not to debate whether WotC's decision was right or wrong, or to say the new Shadow builds are bad (since obviously we haven't seen them, and they're probably fairly good). What I think we all agree on is that the Shadow sub-classes which will apparently be presented are not the classes we wanted WotC to produce, and that we have a right to show them what could've been done.
I don't claim this will be easy. On the contrary, I'm sure making classes that can satisfy all of us will be fairly difficult due to the diversity of opinion. To mitigate this I am taking the initiative to suggest we work on creating a basic archetype for each of the classes we will create, and that we then attempt to work on "builds" of those base classes which present other options.
For example, a Necromancer could begin as a Shadow Controller, and have a build option which allows it to function as a Defender, or as a Leader. We could even go so far as to build entire sub-classes onto the original concept, if the fan community thinks this method is acceptable.
Anyone is free to participate and suggest ideas, or critique others' ideas. If this is going to succeed we'll need people with fresh ideas, but also people who are willing to listen to others' ideas and criticisms. I'm not saying it's going to be easy, but if we all work together, we can make a bunch of classes that will prove to WotC that they made a big blunder by passing up on the idea to make a true Shadow Source.
If anyone wants to volunteer to help, or just offer inspiration or advice, feel free to do so. I'll update the first post as new information becomes available.
