Is o8 a limpers game?

[KneeCo]

I'm a HE player, I wait for a good hand, then I raise PF, that's what I do.

At limit o8 tables though, it seems like I'm the only one raising PF, why is this?

Is raising PF less common in o8 because it's impossible to have a made hand pf or what?

And more importantly than whether it's common or not, is whether it's the correct approach?

It seems to me that if I have a good hand, which I believe is the best hand, I have to raise it up, no?
