The only thing that professions/orders do is to put a leash on you! It limits what your character can become. It limits your options greatly, and with the following rules you could create any character you'd want!
I'm not so vhemently oppsed to professions/orders as some I could name, but I’m still looking for a house rule that will eliminate professions/orders. This may be more than a "house rule" since it changes the game so dramatically. It may also be unsuited for Star Trek, but I think that it could work well in Lord of the Rings atleast. Anyway, here’s a draft:
When you create your character simply avoid choosing a profession/order. You may of course choose a profession/order skill package as normal.
(This is the core of these rules ofcourse. Simply avoid anything in the book that refers to profession or order!)
All through character creation and when assigning picks from advancements, treat all skills as professional/order skills. In other words, you may always purchase skills at a one for one cost. However, during each individual advancement you may not increase your skill ranks with more than 3 picks, though you may acquire as many specialties as you wish.
(This is meant to limit your skill progression since all skills are now profesional/order skills. This might be done in some other way, but I'm not yet sure how else to do it. In the Lord of the Rings game you could say that only racial skills - the once you can use your racial picks for - are available as order skills. But I'd like to eliminate this destinction between skills alltogether!)
At character creation and during all advancements you may pick any ability from any profession/order, as long as you fulfill all of the requisites, if any, for the profession/order you pick the ability from. You must also fullfill the requisites for the ability itself naturally.
(This removes the greates constrain on characters I see it. The limitations of professional/order abilities. Now all abilities will be available to you, and thus your options will be near limitless!)
During advancements, treat all reactions as non-favored and all attributes as favored.
(This I added because I don't see why you shouldn't be able to advance all attributes and reactions at an equal rate, if you only work on them.)
I think that this about covers it.
You must realise that I’m just brainstorming here and I’m looking for feedback. Can it be done?
