Total dissipation goes down proportional to the number of FETs in parallel
(assuming roughly equal current sharing).  Therefore dissipation per device
goes down proportional to the number of FETs squared.  I assumed that's what
you were talking about since the temperature of the FET and heat sinking was
the point of discussion.  In that case you were right the first time.
