Expressly avoided it soooooooooo hard, that they put one in the recent UA.
Fair point, although that's more along the lines of taking spell sniper after taking magic initiate -- those feats work for people who have psionics regardless of how they get it rather than a feat chain that requires a previous feat to access it.
Spend the feat elsewhere then. Psionics isn't for everyone.
Sure, thought I listed that case -- if psionics build to more powerful options then they are unbalanced with non-building feats.
And it appears that all you can do is make negative remarks about the ideas of others. Either start being constructive in your criticism, or stop responding to my ideas.
I'm sorry you feel that pointing out areas that might cause problems is something that should be avoided, Max. I assume, then, that you will never respond or say positive things about psionics with VSM components, or is this more that you dislike constructive criticism of things you like or have presented? You certainly have no problem listing what you don't like from others -- it would be very entertaining to see you take your own advice here and become an only positive commenter.
I'm pointing out that the how you've structured your idea is outside the current design of 5e, not in that it's novel (it's a rehash of prior editions, really), but that it's doing it's thing in a way that fights with the design philosophy of 5e. That's not to say you don't have an idea, but that, if you want to pursue it, you might want to consider how it could be brought inline with that design philosophy. I don't like your idea, so I don't have any motivation to help you design it. I don't dislike your idea (outside of the issues I've pointed out), so I don't have any motivation to prevent you from homebrewing this solution. As for advocating for this to be an adopted solution by WotC, I do have a stake, in that I think this is a poor fit for 5e and would not like to see it be official.
If you want to homebrew in a safe environment, start a + thread for your idea and I guarantee I'll not comment on it. Do it here, and I'll feel free to offer criticism and tell you why I think that criticism is valid and where it applies, just like I did here.
EDIT: and I did ask you what your design goal for doing the random lottery of powers was -- you're free to explain your design rather than complain I don't get it.
