Sure it can benefit from improvements ...
I believe that making it full action would be great improvement ... even tho i cant help the feeling that people would be still complaining that "now there is no reason to do regular attack when i can shove anyone off the cliff to instant death" ... so ... im not quite ure if that improvement would be sufficient. :-/
Well, no, and I don't think why I should explain why that is a problem. But at least in a situation where there is no instant death pit within two screens distance, picking between damage and pushing someone down might be a reasonable choice.
