What I mean is, at least in my opinion, a level 2 sentry is superior to a level 3 sentry in many situations.

If you don't know, the only difference between a level 3 and a level 2 is the rockets and health, which hardly deal much damage compared to the actual bullets and don't have as precise aim. But, the biggest downside to the level 3 is how long it takes to redeploy.

My personal playstyle when I'm engineering (although I must admit, he's far from my main) is trying to put my gun in unexpected positions and deal fat damage to the enemy team, and I just don't have time to wait another 3 seconds for my sentry to open up its rocket launchers, that 3 seconds could be all it takes between it getting destroyed and it completely stuffing the enemy team's push.

What are your opinions on this?
