That's the expected behaviour! \Large is derived by some factor  
(1.44) from normal or default size as given by the preamble. When the  
body's text is \Large the footnote's text is still quite small. When  
everything is scaled, then the footnote's text is also automatically  
enlarged (5 pt -> 7 pt, 6 pt -> 8.4 pt).

Here is an excerpt from a presentation showing font sizes for 10, 11,  
and 12 pt defaults (the last column shows the resolution of the PK  
files):

Email is a wonderful thing for people whose role in life is to be on  
top of things. But not for me; my role is to be on the bottom of  
things. What I do takes long hours of studying and uninterruptible  
concentration.
