What are the penalties for having too many units?

[:P]

I read in-game that people eventually leave your party?
Is it random and do companions leave?

Yeah after some time, if you have too many units in your party they will leave, so make sure not to pass your limit of troops and to have some food for them ready. They also leave because of low moral.
And I don't know about companions. I think they leave if you do things they dislike, but they won't leave because your party is too large. You also can't have to many of them since there is a limit.

There's a separate limit for companions?
If you have too many units, do the weaker ones eventually leave or is it random?

Companion limit is based on your clan level. And about leaving of your troops i am not sure, but i guess its random.
