I don't see how removing the 50 move rule would change very many draws. About the only case I can think of is a King + 2 knights vs. A king + a pawn. I know there are a few other cases but they are pretty rare.
You need to consider more complex endgames. Here are some examples:
I'm sure all of such positions occur much more often than stalemate (or a game that is agreed to a draw because it will eventually end in stalemate).
The only chess players that want to abolish stalemate are those who don't know how to avoid it. Shall we consider abolishing enpassant?
