So anyway, I'm thinking that I am going to go with Plan C as mentioned in the comments of this post. There will be three classes, the Sorcerer, the Adventurer, and the Mastermind (Click to download- also available in the side bar at the left).
In creating this I was very influenced by the Beyond the Black Gate S&W Thief Class and I used Erin D. Smale's Building the Perfect Character Class to get a baseline for xp requirements and such. I found both of these at the OSR Links to Wisdom page.
My sincere thanks to everyone involved with everything above (including S&W).
I'll likely change this up a bit in the future, but probably only a bit.
I can invent monsters and technogear and spells all day, but making classes has been the major stumbling block for me, and I feel that I am on the right track at last. I could be just a few weeks away from play test document.
