So... I'm not reraising PF anymore. Is that wrong?

Ok, I'm talking about deepstack poker. 40bb+. Is this really bad? 3 examples from a recent $1000 live tourney I just played.

blinds 25/25
4 limps, button makes it 150. I call in the SB with QQ.

Blinds 75/150
HJ opens to 450. I call with AJo in the CO.

Blinds 100/200
CO opens to 600. I call with AA on the button.

My reasoning varies slightly with each hand, but essentially, it is the same: I WANT some sort of action with all of these hands and adding 4.5BB to my 50BB stack (with the risk of having to fold to a shove and losing 8BB) is not incentive enough to be 3betting.... I mean re-raising. Thoughts?
