having a multiplier LA means your BAB, saves, skill points, and all other level dependent benefits start out vaguely okay (a 2nd level gestalt character [ecl 3] is one level down) but they quickly get out of hand (a 10th level gestalt [ecl 15] is completely crippled in a way that no classes abilities can make up for.)
I thought about it and realized that the benefits were fairly minor, really, about the same as having a cohort of your level that can't take their own actions, or go off to do other things... so on and so forth. I realized that rather than having a multiplier for a la, it might work better to have a flat bonus, of about +2. Does that sound about right?
the other thing is the fact that LA sucks, it's screws up HD, skills, saves, attack bonus, and pretty much every other level dependant thing, and it's really not worth a level, generally speaking. I was thinking it might work if a LA gave you, essentially, commoner HD.
so, each point of LA would give you:
- d4 HD
- 2+Int skill points
- poor bab
- no good saves.
