I didn't like any of the options for question 4.
I know! None were satisfactory, at all.
I think Pathfinder actually has my favourite solution so far, though I think it needs work. The remaining problems probably have to do with the CR system and backwards comparability.
So, my ideal solution would resemble something like.. level adjustment to enter, then possibly reducing that adjustment (gaining back those lost levels in some way) as you advance further. If you do this, you can let nearly ALL monsters be characters, assuming the adjustment comes in high enough. And that is what I need, I have had a wide range of monster PCs and I would hate to lose that club in my bag of tricks. Most people won't be, but that doesn't mean that I should not be allowed the option.
Beyond that however, I've had excellent experiences with Ogre PCs, TERRIBLE experiences with Pixies (mostly due to one specific player) and I don't consider the stock humanoids (aasimar, orc, etc.) to be any different than regular PCs. I haven't had anyone (yet) who was high enough to be able to be a true dragon, but I have had several express interest and a few come close and I absolutely want them to be playable in the future - my preferred system already does that and the system I am developing does that, I would be amazed if WotC can't figure out a way. My game would absolutely suffer if they limit it to only humanoids and not expand it as far as possible.
Oh, and weak versions of monsters
CAN work, but I have not seen it ever work in reality. It always feels very much like a weak form of that creature. Play a weak angel and you feel it as soon as you encounter a real one, any fiend, or really any outsider at all. I don't like having only some of the powers that I feel are iconic to a creature
*.
Also, unless I'm crazy, it seems like a partial solution for this 'weak form' of a monster might be to let PCs play the 'Half' version. It isn't enough for my preferences, but it is something and does allow a partial measure without feeling, unjustifiably IMHO, watered down. That is, if you want to play a ogre but it is too strong then play a half-ogre. Want to be draconic, half-dragon. Want to be a celestial but the real ones have too many powers? Half-celestial. It can even work with what Wyatt was saying about large creatures being too powerful, as half-creatures could all (by design) end up all being medium (possibly small). They don't even have to be a template (as it was in 3e) they could just be a stock race. Not half-dragon-half-human; just half-dragon. Period.
Also, does anyone else find it funny that we got an article like this AFTER the shadar-kai? I mean, given the percentages and the conversation we had when the shadar-kai article did come out; I would assume monster PCs are more popular.
*If they are not iconic then why does a "fully formed" version of that creature exist, and why with that exact set of powers?
