Pot sized bet overused in NL poker?

If you raise with big cards, miss and want to make a continuation bet - 1/2 pot is normally right to get the best odds on your bet (only has to take it down 1 out of every 3 times)

If you raise with a big hand and do not improve on the flop, it seems a 1/2 - 3/4 pot sized bet would cose you less chips for those times you meet a lot of resistance and have to let it go.

The only times I really use pot sized bets is when I have the nuts or near nuts and I think my opponent has a very strong hand also, or if I flop a monster on a draw heavy board QQ on a QJ9 with two suits for example.

So if I play against you, I can always tell how good your hand is by how much you bet? You don't see the drawback to that?
