@Grefter: A little of both. I build CCP1 while learning how to make a patch and there was a lot of bad choices in how to apply things on top of the whole patch being a disorganized mess and having almost no notes on what changes I'd actually made. Also, in the year or so it took me to make that many more and cleaner hacks have been produced to do the same things I was already doing, usually in more stable ways. On top of that there are just more options for changing things than I had before [like binding Act commands to skillsets and equipment or applying +Brave and +Faith modifiers to equipment] in ways I really wanted to experiment with. There have been a few jobs that got reworked or replaced entirely as well as many more modifications to monster families as well.
@Bobbin: I can't promise balance like LFT or even much better than Vanilla...which is really the major reason for releasing a beta version. I need to get feedback from people that understand balance better than I do so I can find out if my planning worked even half as well as I hoped.
