Ok i play too tight then?

My stats are 17% VPIP and ~8.5% PFR. (W@SD is like 52%)
I play position (obv) but find at $25 NL a lot of players are raising before it gets to me in LP and i've been folding AJo/J-10o etc if someone has raised before me. Calling with PP, Suited connectors, AQ+, AJs+, A2s-A5s

I raise with good cards, Axs, A-10o+, PP, SC on the button/cut off, but still my stats seem a LOT lower than you guys.
Is this strat ok for $25 NL? When do i need to start losening up? What cards are ok to play after villain with no reads (multitabling lots) raises in MP?

Cheers,
Clar
